Question

Javier wants to prove that triangle MNP is similar to triangle RSP.

What missing piece of information does Javier need to prove that triangle MNP is similar to triangle RSP by the Angle-Angle Similarity Postulate?

A. Javier needs to know the measure of angle P.

B. Javier needs to know the measure of angle M.

C. Javier needs to know the measure of angle S.

D. Javier needs to know that segment MN is parallel to segment SR.

Answer 1

Explanation:

In triangles MNP and RSP, if there are two pairs of corresponding angles that are congruent or equal, it means that

triangle MNP is similar to triangle RSP. The corresponding angles in both triangles are

P corresponding to P

M corresponding to R

N corresponding to S

Therefore, the missing piece of information that Javier needs to prove that triangle MNP is similar to triangle RSP by the Angle-Angle Similarity Postulate is

A. Javier needs to know the measure of angle P.

Answer 2

D. Javier needs to know that segment MN is parallel to segment SR.

Explanation:

(I know this is old, but I wanted to answer if anyone else comes to this.)

If Javier does not know if segment MN is parallel to segment SR, he would not be able to prove that the two triangles were similar.
