Slope Triangles and Similar Figures Review WS
Graph each pair of similar triangles. Then write a proportion comparing the rise to the run for each of the similar
slope triangles and determine the numeric value. Then connect the two triangles with a slope line.
1. ∆EFG with vertices E(6,9), F(6,5), and G(4,5); ∆GHI
with vertices G(4,5), H(4,1), and I(2,1)
2. ∆DEF with vertices D(6,5), E(6,2), and F(2,2);
∆FMW with vertices F(2,2), M(2,–4), and
W(-6,–4)
