	Chapter 8 : Similarity 8.1 Problem Solving Help

Lesson 8.1: Help for Exercises 57 and 58 on page 463 Since the ratio of side lengths of PQR to the corresponding side lengths of STU is 1:3, then the following three relationships can be written as equations. For Exercise 58, it may be helpful to rotate PRQ 180 ° so that corresponding sides are easier to see. You can use equations to find PR and ST, the Pythagorean Theorem to find RQ, and an equation or the Pythagorean Theorem to find UT.
