Lesson 6 Homework Practice

Slope and Similar Triangles

Graph each pair of similar triangles. Then write a proportion comparing the rise to the run for each of the similar slope triangles and find the numeric value.

1. EFG with vertices E(1,9), F(1,5), and G(2,5); GHI with vertices G(2,5), H(1,2), and I(3,1)

2. JNL with vertices J(-3,3), N(-3,-3), and L(5,-3); KML with vertices K(1,0), M(1,-3), and L(5,-3)
