oh, ok.
Landon34
  • Landon34
No, it doesnt need one.
Shalayla4
  • Shalayla4
Lol. What is the theorem . And yes, it does need one.. It's highlighted so there has to be one.. I guess, teacher highlighted what needs to go.
Landon34
  • Landon34
well, I would ask your teacher for help, I would be wrong, if I tried to figure it out.
Shalayla4
  • Shalayla4
Ohkay, how do I show that I got the answer I got though?
Shalayla4
  • Shalayla4
She can't help me, that's why I posted it. She is working with students taking finals
Landon34
  • Landon34
are you homeschooled, privite school, or public?
Shalayla4
  • Shalayla4
Homeschool. (online)
Landon34
  • Landon34
Ok, Im in privite school, (Enlightium christian academy) and I dont know how online school works, but you need help from someone who knows what they are doing. ( your parents, big brother,etc)
Shalayla4

Ohhp ahaa my bad..
Hope210
  • Hope210
yeah I'm in 9th grade so this doesn't make much sense either but I know someone you might be able to help

@pogo it's at the top ^.~

  • pogo
~(^_~)~ so you need answer to what that theorem is?
Shalayla4
  • Shalayla4
Yas, and how I solved the problem.. I guess.. whatever the blank one at the bottom says ..
Shalayla4
  • Shalayla4
"Show and explain how to obtain the answer given" The answer I put in red..
pogo
  • pogo
jst a sec i made a typo
pogo
  • pogo
okay this is the theorem-> whenever 2 parallel lines are cut by a transversal then the alternate exterior angles are always equal and for this-"Show and explain how to obtain the answer given" the answer will be-> Since AB||CD, by the Corresponding Angles Postulate, angle1 is congruent to angle5. Also, by the Vertical Angles Theorem, angle5 is congruent to angle7. Then, by the Transitive Property of Congruence, angle1 is congruent to angle7. You can prove that angle4 and angle6 are congruent using the same method.

Whheeelll thaan . Thanks love!! Haha Now, I have 4 more xD

That's two, I just don;t get it !!! Agghhh!!
pogo
  • pogo
okay :) The sum of all the angles inside a triangle is 180 degrees so the sum of all angles is 180 so \(25+120+x=180\) now can you find x from here?
Shalayla4
  • Shalayla4
Indeed . c:
pogo
  • pogo
:) so what is the value of x that you got :D
Shalayla4
  • Shalayla4
145
Shalayla4
  • Shalayla4
Wait no
Shalayla4
  • Shalayla4
WWWWWWAAAIIITTTT!!!!
pogo
  • pogo
okay :)
Shalayla4
  • Shalayla4
35 c:
pogo
  • pogo
yeah correct :D
Shalayla4
  • Shalayla4
So my answer is 35, right?
pogo
  • pogo
yes
Shalayla4
  • Shalayla4
Okay, so theorem?? .-.
Shalayla4
  • Shalayla4
And then showing my answer bleeeccchhhh..
pogo
  • pogo
the theorem will be-> Interior angle sum property the sum of all angles inside a triangle is 180
pogo
  • pogo
shyla?
Shalayla4
  • Shalayla4
Sorry, I was trying to figure it out, got it.. and *Shayla Lol
pogo
  • pogo
lol okay :) if you get stuck feel free to ask :D
Shalayla4
  • Shalayla4
Ohkay, I got this :p So How would I explain how I got my answer though?
pogo
  • pogo
okay explain it like this-> Using interior angle sum property of triangles we can write- 25+120+x=180 145+x=180 145+x-145=180-145 x=35
Shalayla4
  • Shalayla4
Ohhhh Okaaayyyy!!
Shalayla4
  • Shalayla4
Ugh third one..

pogo
  • pogo
okay so here \[\frac{ ST }{ RU }=\frac{ RU }{ QV}\] we know SU and RU just substitute the values to get QV ugh i can't recall the theorem >_
Shalayla4
  • Shalayla4
Ahh I see and dang it! :/ That's otaaayyy! c: Thanks love! And how would I explain that?
Shalayla4
  • Shalayla4
And you mean we know ST and RU not SU :)
pogo
  • pogo
oh lol yes ST cx
Shalayla4
  • Shalayla4
So it's 59.59?
pogo
  • pogo
okay i have an explanation tho but can you tell me which chapter is it related to because i have an explanation related to triangles
Shalayla4
  • Shalayla4
Uhmmmm I have no clue, I look at lessons not a book :/
pogo
  • pogo
okay were the lessons related to triangles or parallel lines or something else?
Shalayla4
  • Shalayla4
The units were on Congruent Polygons & Special Quadrilaterals && Polygon Basics
Shalayla4
  • Shalayla4
Hey, is my answer 59.59 tho? That's what I got...
pogo
  • pogo
yeah your answer is correct
Shalayla4
  • Shalayla4
Yay!
Shalayla4
  • Shalayla4
You there??
pogo
  • pogo
but the explanation i have is this-> Line passing through the midpoints of the non parallel sides of a trapezium is parallel to the other two sides so since|dw:1450209116843:dw| here corresponding angles are equal so by this property we can say-> QV||RU angle1=angle5 angle 2= angle 6 RU||ST angle 3=angle 7 angle4=angle8 so since all the angles are equal trapeziumQVUR is similar to trapezium RUST so the ratio of sides will be equal so\[\frac{ ST }{ RU }=\frac{ RU }{ QV }\]
pogo
  • pogo
hah cut that "but" in the starting :) i recalled the proof
Shalayla4
  • Shalayla4
Can you dumb that down o.o I'm not smart xD
pogo
  • pogo
we just proved that trapeziumQVUR and trapeeziumRUST are similar so the ratio of corresponding similar sides must be equal so \(\frac{ ST }{ RU }=\frac{ RU }{ QV }\) and we used this result and substituted given values to get the answer.
Shalayla4
  • Shalayla4
Trapezium?
pogo
  • pogo
trapezium is a type of quadrilateral which looks likes this->|dw:1450209889242:dw| trapeziums have 2 opposite parallel sides in this figure AB and CD are parallel
Shalayla4
  • Shalayla4
Ohhhh okayyy. Lol

Thank you so much for taking the time to even help me :/
pogo

in the given figure angleABC=angleCDE (given) angleACB=angleECD (vertically opposite angles are equal) and sideBC= sideCD (given) so therefore these 2 triangles are congruent by ASA(Angle-Side-Angle property)
pogo
  • pogo
haha np (;
Shalayla4
  • Shalayla4
So given the ASA property, that's my theorem right?
pogo
  • pogo
yes :)
Shalayla4
  • Shalayla4
Yay I'm getting it! c: Okay so I'm confused on what the answer is then?
pogo
  • pogo
the explanation?
adelyn_helps
  • adelyn_helps
What grade is this
Shalayla4
  • Shalayla4
10th and that's what I meant @pogo :p
Shalayla4
  • Shalayla4
Wait, the answer I need to put is ASA and use the same answer for the Theorem?
pogo
  • pogo
okay this is the explanation- in the given figure angleABC=angleCDE (given) angleACB=angleECD (vertically opposite angles are equal) and sideBC= sideCD (given) so therefore these 2 triangles are congruent by ASA(Angle-Side-Angle property)
Shalayla4
  • Shalayla4
That's the whole explanation? But the ASA part is my answer for the top right hand box, right?
pogo
  • pogo
so you want the explanation to why the ASA property works?
Shalayla4
  • Shalayla4
Wait.. So this answer you gave me is which part?? Answer, Theorem, or Explanation? ""In the given figure
pogo
  • pogo
the theorem used is-> ASA theorem the explanation to why the two triangles are congruent by ASA is -> In the given figure
Shalayla4
  • Shalayla4
Ahhh, Sorry I'm difficult.. :/
Shalayla4
  • Shalayla4
Okay I see it now, phew.. Got it.. One more then you don't have to deal with me anymore c;

  • Shalayla4
JK is 18cm right?
pogo
  • pogo
yeah :D
Shalayla4
  • Shalayla4
Okay, now how do I figure out the theorem I "used" lol
pogo
  • pogo
:D Side opposite to equal angles are equal in length
Shalayla4
  • Shalayla4
What do you mean? So point K equals 28cm? UGH Idk :(
pogo
  • pogo
no :) i mean like-|dw:1450211669636:dw| in this figure angleABC=angleACB <-- this is given and we can see that side opposite to angleABC is AC and side opposite to angleACB is AB according to the theorem -sides opposite to equal angles are equal so AB=AC
Shalayla4
  • Shalayla4
Ohhh So my theorem is "Because sides opposite to equal angles are equal, that means AB is equal to AC" Right?
pogo
  • pogo
yeah in your case KJ=LK :)
Shalayla4
  • Shalayla4
Well yea, silly c: Okay So How Do I Explain That?
pogo
  • pogo
explanation is-> the two angles are equal in the triangle so this means that the triangle is isosceles and in isosceles triangle the sides opposite to the equal angles are equal so KJ=KL
Shalayla4
  • Shalayla4
It's not fair!! stahhpp being so smmaarrtt!!! -.- C:
Shalayla4

You are LITERALLY my lifesaver!!! Thank you so much!!!!! Message me. If you want to still deal with muaahhh xD
