11.6 Perimeters and Areas of Similar Figures 1/19/17

Example 1 Find the missing side lengths. Then find the ratio (small to big) of the perimeters of these similar regular trapezoids.

Perimeters of Similar Figures The ratio of the perimeters of similar figures is equal to the ratio of their corresponding side lengths

Example 2 These triangles are similar. Find: The missing side length The ratio of the sides (small to big) The ratio of the areas (small to big)

Areas of Similar Figures The ratio of the areas of similar figures is equal to the square of the ratio of their corresponding side lengths
