Question

Are the two triangles similar? How do you know?

a. No
b. Yes; by AA ~
c. Yes; by SAS ~
d. Yes; by SSS ~

Answer 1

the corresponding angles must be equal. Since m∠R and m∠S are not equal, the triangles are not similar.

Step-by-step explanation:

Given:

m∠R=80∘ in △PQR

m∠S=70 ∘ in △STU

If △PQR and △STU are similar, the corresponding angles must be equal. Since

m∠R and m∠S are not equal, the triangles are not similar.

Therefore, the correct answer is:

a. No
