# Chapter 1 - Trigonometric Functions - Section 1.2 Angle Relationships and Similar Triangles - 1.2 Exercises: 42

BA corresponds to QP AC corresponds to PR CB corresponds to RQ

#### Work Step by Step

1.Angles labeled on the diagram correspond, you just need to pair them up as congruent $\angle B - \angle Q$ $\angle A -\angle P$ $\angle C - \angle R$ 2. You just need to look: if both angles on the line correspond, then the lines correspond. Sounds like tautology, but you just need to focus on angles first, then on the sides. You will get $AB -PQ$ ;$BC- QR$; $CA- RP$ lines corresponding to each other.
