Question

Please Help !! ASAP ill Give A MEDAL!!!

Answer 1

Which postulate can be used to prove the two triangles below are similar? Explain your answer using complete sentences, and provide evidence to support your claims.

Answer 2

I don't understand your problem. It is so clear that 2 triangles are similar. \[C = 180^{o} - A - B\] and similarly with the other triangle. Two triangles are similar iff all of their angles are equal. Did it answer your question?

Answer 3

Can you kinda be more specific ? I dont understand it

In your problem, we used AAA (angle angle angle) postulate.

Step1: Calculate 3 angles of both triangles by using the theorem: in every triangle, the total sum of three angles always 180 degree. Then we must have A + B + C = 180, A' + B' + C' = 180

Step2: Check if 3 angles is equal with each other. We can see A = A' =50, B = B' = 33, C = C' = 97

"How to tell if triangles are similar
Any triangle is defined by six measures (three sides, three angles). But you don't need to know all of them to show that two triangles are similar. Various groups of three will do. Triangles are similar if:
AAA (angle angle angle)
All three pairs of corresponding angles are the same.
See Similar Triangles AAA.
SSS in same proportion (side side side)
All three pairs of corresponding sides are in the same proportion
See Similar Triangles SSS.
SAS (side angle side)
Two pairs of sides in the same proportion and the included angle equal.
See Similar Triangles SAS."
