1
8.6 Perimeters and Areas of Similar Figures (1 card)

2
Perimeters and Areas of Similar Figures If the similarity ration is, then: The ratio of the perimeters is The ratio of the areas is

3
Ex 1: The trapezoids are Similar Find the similarity ratio (of the top shape to the bottom shape) Find the perimeter ratio (of the top shape to the bottom shape) Find the area ratio (of the top shape to the bottom shape)

4
Ex 1: The trapezoids are Similar Find the similarity ratio Find the perimeter ratio Find the area ratio

5
Ex 1: The trapezoids are Similar Find the similarity ratio Find the perimeter ratio Find the area ratio

6
Ex 1: The trapezoids are Similar Find the similarity ratio Find the perimeter ratio Find the area ratio
