this is super cool website https://www.mathsisfun.com/geometry/parallel-lines.html
scroll down a little you will see this http://prntscr.com/8ksit6 practice
got it ? :=)
u there ?
sorry my mom made me go for some ice and no not quit well could you explain
just ice or icecream yummmm ...
no jus t ice for some tea i wish it was icecream
but anyways could you explain
lol it's okay
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
and a= d ?
let's say angle b = 20 degree so then angle c =20 bec both angles are the same b = c
ok ok i got it intill there but i still dont understand what the answer is
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
yea but isnt the operation mad aready ? dont i just have to get the diffinicions
yes right so what's the definition ? angle 2 = angle 4
is it the given ?
or diffinitopm of congruuent angles ?
given is angle 2 =110 and angle 4 = 110 so what's the definition ?
|dw:1443300346320:dw| what would be the definition
what's alternate exterior angles ?
|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
im really lost i dont quite understand
well take some time practice on this link scroll down a little where u see `choose one`
it tells u the answer http://prntscr.com/8ktbql
ok give me a sec too lok at it
would the answer be transversal
|dw:1443300776381:dw| replace b with 2 and g with 4 now that pic is same as ur question
according to alternate exterior angles angle b and angle g are the same
so is it vertical angles than
how is it vertical what's the definition of vertical angles ?
isint it two angles that are vertical and equal the same ?
vertical angles that are opposite of each other |dw:1443301018790:dw|here a and b are vertical angle s
angle 4 is outside the lines so the definition should hve the exterior word
would it be alternative exterial angles then ?
so b would be that then ?
yes right ..
ok is c Supplementary Angles
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
so i would name them linear pair then ? what is the diffreance
but there is that same word in the other two woudnt it like be wrong ?
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
|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
ok i think i understand so would the answer to C be linear pair?
yes right bec angle 3 and 4 formed a striaght line
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 ?
angle 4 and angle 3**
would those be supplementery angles ?
or corrisponding angles
what is the definition of corresponding angle s?
to angles that are the same like |dw:1443348941009:dw|
am i right ?
yyee right but we are looking at angle 3
|dw:1443349090771:dw| would it be like that then ?
yes right but i don't think is corresponding angles bec |dw:1443302711965:dw| they didn't give u the angle
am i wrong ?
well the definition is right but i don't think they r looking for corresponding angles
it can be supplementary angles or linear pair
both are the same bec angle 4 is 110 and angle 3 is 70 so both angles add up to what ?
to 180 ? and but woudnt it be wrong fro the two lat quwestions to have the same answer
|dw:1443303060274:dw| there didn't mentioned any angle so how would we say corresponding hmmm
|dw:1443349689960:dw| Im confued i thought we were answering this one ?
ok well in that case i got no idea what to put in that one could you give me a clue
i'll go with supplementary angles bec if angle 4 is 110 then angle angle 3 is 70 add up to 180
or maybe not let me confirm it
im really lost
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
i'll wait for freckles reply
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......
inshort the question is: is it okay to write both linear pair and supplementary angles for c ?? @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
ye right i don't what they are looking for they already mentioned it |dw:1443305571012:dw|
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 >>
ok so how would it all go then ? and thanks for helping you two! i really aprecvhiate it
lol I just don't get it why would they ask a question they already gave the answer to
well i think that you just have to give the explainating of what they are doing
@panfilo084 but they already explained why they have <3+<4=180
so then just write definition
the reasons being because they are a linear pair and therefore supplementary
so how would it tueen out to be then ?
lol, c = supplementary and linear bec you said so
are you sure ?
no i was kidding...
ok ok so what sthe answer then ? im real confued
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
let angle 3 = x \[110+x=180\] can you solve for x ?
angle 3= 70
or x= 70
for c I would just say "definition of supplementary angles"
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
though to me it seems repetitive
i think they are testing ur reading skills

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
I guess they want to be sure you know the definition of supplementary angles like they want to be really sure
oops page 6
well I already told you what I thought answer c was
well can you make something like i did soo i could now which ones to put ?
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
for D ^
thanks what anout B and C
and for c i'm agree with frec supplementary angles :D
b is correct
ok so is that all ? are we done with this one ?
well for c I would say definition of supplementary angles
d I would just say I solve the equation above by subtracting :p
subtraction for short don't know if that is the correct phrase they are looking for
but that is what was done to get the result next to d
it's okay to show some work you know some teachers are like ...... >.<
true well hopefully its righ beacuse its worth a lot of points
ye good luck.....
