Similar Polygons (10.7) HW: 10.7 (1-8, 13-22)

Essential Question: How do the areas and perimeters of similar shapes compare?

similar proportional

P=52 P=78

Small Area=160 Big Area=360

Scale Factor: Ratio of P: Ratio of A:

Two kites are similar with a scale factor of. If you know the area of the smaller kite is 72 square inches, what is the area of the larger kite? Ratio of A: x= 162 in 2
