### 11.3 Perimeters and Area of Similar Figures

Similar Polygons

Remembering Similar Polygons

Similar polygons have all the Angles congruent and the Sides have the same ratios. (like these three houses)

Remember this Theorem

If two polygons are similar (equal angles and corresponding sides in ratios), then the perimeters ratio is the same as the scale factor.

Perimeters are 24:16

same ratio as 3:2 for the sides

Theorem

If two polygons are similar (equal angles and corresponding sides in ratios), then the Area ratio is the same as the scale factor squared. (in the regular hexagons)
