Answer 1

Answer: Angle-Angle Similarity Theorem

Step-by-step explanation: We know the angles inside a triangle must add up to 180 degrees.

Triangle ABC: 37+78+x=180, we get that x=65 degrees

Triangle PQR: y+78+65=180, we get that y=37 degrees

Angle-Angle Similarity Theorem states that if two angles of one triangle are congruent (equal) to two angles of another triangle, then the two triangles are similar.
