2 SIMILAR TRIANGLES Similar figures have the same shape, but are a different size.

3 SIMILAR TRIANGLES Corresponding sides of similar figures are proportional. 2" 4" 3" 6"

4 SIMILAR TRIANGLES Using proportions, we can find the lengths of missing sides of similar figures. 6" 12" 4" ?

5 SIMILAR TRIANGLES 6" 12" 4" x = x

6 6" 12" 4" x = x x = 48÷6 = 8"

7 SIMILAR TRIANGLES 6" 12" 4" ? = x

8 6" 12" 4" x = x x = 48÷6 = 8"

9 SIMILAR RECTANGLES 7"x 4" x 8"

10 7"x 4" x 7 x 4 = 8 8"

11 7"x 4" x 7 x 4 = 8 8" x = 14"

12 SIMILAR RECTANGLES 7"x 4" x 7 4 x = 8 8"

13 7"x 4" x 7 4 x = 8 7.5" x = 14"

14 SIMILAR RECTANGLES 5" 8" x 10"

15 5" 8" x = x 10"

16 5" 8" x = x 10" x = 16"

17 SIMILAR RECTANGLES 5" 8" x = x 10"

18 5" 8" x = x 10" x = 16"
