Triangle MNO is dilated to form new triangle PQR. If angle is congruent to angle R. what other information will prove that the two triangles are similar by the AA similarity postulate?

A) Side ON is congruent to side RQ.
B) Angle N is congruent to angle Q.
C)Side MN is congruent to side PQ.
D)Angle M is congruent to angle Q.

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc

step-by-step explanation:

the answer is 128
