Question

Given: XY/AB=XZ/AC and ∠A ≅ ∠X

Prove: ΔABC ~ ΔXYZ

Answer 1

Have a diagram?

Answer 2

No that,s how it was...all it
was explaining was Proving SAS Similarity by Dilation

Answer 3

Well, "SAS" is pretty much a theorem that englobes the similarity of two triangles.
In short words:
"If a pair of triangles have a two pairs of similar angles and the angles between them are also congruent, then, the two triangles are similar."

Answer 4

oh okay thank you!

Answer 5

And in the excercise you are given that two sides are similar and also the angles inbetween are congruent, therefore ABC and XYZ are similar.
