this is super cool website
https://www.mathsisfun.com/geometry/parallel-lines.html

- Nnesha

scroll down a little you will see this

practice

- Nnesha

got it ? :=)

- Nnesha

u there ?

- anonymous

sorry my mom made me go for some ice and no not quit well could you explain

- Nnesha

just ice or icecream yummmm ...

- anonymous

no jus t ice for some tea i wish it was icecream

- anonymous

but anyways could you explain

- Nnesha

lol it's okay

- Nnesha

alright well if you just look at the link i gave u u will definitely get the answer
: alternate exterior angles
exterior means outside of two parallel lines
so alternate exterior angles opposite side of transversal lines |dw:1443299612783:dw|
in this example
b and c are alternate exterior angles
and alternate exterior are equal
so you can write b=c

- anonymous

and a= d ?

- Nnesha

yes right

- Nnesha

let's say angle b = 20 degree
so then angle c =20
bec both angles are the same b = c

- anonymous

ok ok i got it intill there but i still dont understand what the answer is

- Nnesha

now look at ur original question
given is angle 2 =110
and angle 4 =110 both angles are equal
and both angles are outside the two parallel lines

- anonymous

yea but isnt the operation mad aready ? dont i just have to get the diffinicions

- Nnesha

yes right so what's the definition ?
angle 2 = angle 4

- anonymous

is it the given ?

- anonymous

or diffinitopm of congruuent angles ?

- Nnesha

given is angle 2 =110
and angle 4 = 110 so what's the definition ?

- Nnesha

|dw:1443300346320:dw|
what would be the definition

- anonymous

m<2+m<4 ?

- Nnesha

what's alternate exterior angles ?

- Nnesha

|dw:1443300519812:dw|in this example
a and d are alternate exterior angles
you just said a=d so yes alternate exterior angles are equal

- anonymous

im really lost i dont quite understand

- Nnesha

well take some time
practice on this link
scroll down a little where u see `choose one`

- Nnesha

it tells u the answer http://prntscr.com/8ktbql

- anonymous

ok give me a sec too lok at it

- anonymous

would the answer be transversal

- Nnesha

|dw:1443300776381:dw|
replace b with 2 and g with 4
now that pic is same as ur question

- Nnesha

according to alternate exterior angles angle b and angle g are the same

- anonymous

so is it vertical angles than

- Nnesha

how is it vertical what's the definition of vertical angles ?

- anonymous

isint it two angles that are vertical and equal the same ?

- Nnesha

vertical angles that are opposite of each other |dw:1443301018790:dw|here a and b are vertical angle s

- Nnesha

angle 4 is outside the lines so the definition should hve the exterior word

- anonymous

would it be alternative exterial angles then ?

- Nnesha

yes right

- anonymous

so b would be that then ?

- Nnesha

yes right ..

- anonymous

ok is c Supplementary Angles

- Nnesha

yes right or in other words you can say linear pair |dw:1443301315927:dw| in this exxample a and b are linear pair
add up to 180 degree

- anonymous

so i would name them linear pair then ? what is the diffreance

- anonymous

but there is that same word in the other two woudnt it like be wrong ?

- anonymous

|dw:1443348098679:dw|

- Nnesha

no
there is a little difference
supplementary angles can be any two angles that add up to 180 degree
but linear pair should be adjacent

- Nnesha

|dw:1443301681893:dw| angle a and b can be equal to 180 but they are not linear pair
linear pair should form a straight line

- anonymous

ok i think i understand so would the answer to C be linear pair?

- Nnesha

yes right bec angle 3 and 4 formed a striaght line

- Nnesha

straight *

- Nnesha

so remember angle 4 and angle 4 must add up to 180 they are supplementary angles as well so
what would be the last one ?

- Nnesha

angle 4 and angle 3**

- anonymous

would those be supplementery angles ?

- anonymous

or corrisponding angles

- Nnesha

what is the definition of corresponding angle s?

- anonymous

to angles that are the same like |dw:1443348941009:dw|

- anonymous

am i right ?

- Nnesha

yyee right but we are looking at angle 3

- anonymous

|dw:1443349090771:dw|
would it be like that then ?

- Nnesha

yes right but i don't think is corresponding angles bec |dw:1443302711965:dw| they didn't give u the angle

- anonymous

am i wrong ?

- Nnesha

well the definition is right but i don't think they r looking for corresponding angles

- Nnesha

it can be supplementary angles or linear pair

- Nnesha

both are the same
bec angle 4 is 110 and angle 3 is 70
so both angles add up to what ?

- anonymous

to 180 ? and but woudnt it be wrong fro the two lat quwestions to have the same answer

- Nnesha

|dw:1443303060274:dw|
there didn't mentioned any angle so how would we say corresponding hmmm

- anonymous

|dw:1443349689960:dw|
Im confued i thought we were answering this one ?

- Nnesha

yes

- anonymous

ok well in that case i got no idea what to put in that one could you give me a clue

- Nnesha

i'll go with supplementary angles bec if angle 4 is 110 then angle angle 3 is 70 add up to 180

- Nnesha

or maybe not let me confirm it

- Nnesha

@freckles

- anonymous

would this be correct

##### 1 Attachment

- anonymous

im really lost

- Nnesha

well if that's my work i would also put supplementary angles
angles that add up to 180 degree and ofcouse when a straight line formed it is add up to 180
i would put both linear pair and supplementary
you can write a little definition with it

- Nnesha

i'll wait for freckles reply

- Nnesha

C go with supplementary angles
bec the given is m<3+m<4 =180
both angles add up to 180 so yes supplementary would be goood......

- Nnesha

inshort the question is:
is it okay to write both linear pair and supplementary angles for c ?? @freckles

- freckles

well a linear pair are supplementary
why would they be looking for linear pair or supplementary?
they already said 3 and 4 are both of those..
it just seems repetitive to say is again
but that is true <3+<4=180 since the angles <3 and <4 are supplementary
and they are supplementary for the reason that they are a linear pair

- Nnesha

ye right
i don't what they are looking for they already mentioned it |dw:1443305571012:dw|

- Nnesha

know*

- Nnesha

we have to prove that angle 3 equal 70
so if if angle 4 and 3 are supplementary
and the given is angle 4 =110
110 + angle 3 =180
solve for angle 3 you will get 70
so i'm pretty sure it's okay to repeat the same definition for C and D
right or not >>

- anonymous

ok so how would it all go then ? and thanks for helping you two! i really aprecvhiate it

- freckles

lol I just don't get it
why would they ask a question they already gave the answer to

- anonymous

well i think that you just have to give the explainating of what they are doing

- Nnesha

ikr :/

- freckles

@panfilo084 but they already explained why they have <3+<4=180

- Nnesha

so then just write definition

- freckles

the reasons being because they are a linear pair and therefore supplementary

- anonymous

so how would it tueen out to be then ?

- Nnesha

lol,
c = supplementary and linear bec you said so

- anonymous

are you sure ?

- Nnesha

no i was kidding...

- anonymous

ok ok so what sthe answer then ? im real confued

- Nnesha

for D
you can say
given is angle 4 = angle 2
and angle 4 = 110
and according to the definition of linear pair \[\rm 110+ angle~ 3=180\]
now solve for angle

- Nnesha

let angle 3 = x \[110+x=180\] can you solve for x ?

- anonymous

angle 3= 70

- Nnesha

proved.

- anonymous

or x= 70

- freckles

for c I would just say "definition of supplementary angles"

- freckles

the definitely of supplementary angles :
a and b are supplementary if a+b=180
and you have <3+<4=180 so that means the definition of supplementary angles was applied

- freckles

though to me it seems repetitive

- Nnesha

i think they are testing ur reading skills

- Nnesha

lel

and here they do the same thing on page 4

- anonymous

well can either of you like put the answers in order beacuse i got confueds woud
b= altnate exterior algles
C linear pair and sumplemetary
D= sumplñementary angles
are these answers correct

- freckles

I guess they want to be sure you know the definition of supplementary angles
like they want to be really sure

- freckles

oops page 6

- freckles

well I already told you what I thought answer c was

- anonymous

well can you make something like i did soo i could now which ones to put ?

- Nnesha

well i'll put some extra information bec i'm not exactly sure
if that's my worksheet
i'll answer it like this
given is angle 4 = angle 2
and angle 4 = 110
and according to the definition of linear pair \[\rm 110+ angle~ 3=180\]
angle = 180-110=70

- Nnesha

for D ^

- anonymous

thanks what anout B and C

- Nnesha

and for c i'm agree with frec
supplementary angles :D

- Nnesha

b is correct

- anonymous

ok so is that all ? are we done with this one ?

- freckles

well for c I would say definition of supplementary angles

- Nnesha

yes.. done....

- freckles

d I would just say I solve the equation above by subtracting :p

- freckles

subtraction for short
don't know if that is the correct phrase they are looking for

- freckles

but that is what was done to get the result next to d

- Nnesha

it's okay to show some work
you know some teachers are like ...... >.<

- anonymous

true well hopefully its righ beacuse its worth a lot of points

- freckles

good luck

- Nnesha

ye good luck.....

- anonymous

thanks
