1. Ratio of Similitude

2. The ratio of similitude of two similar polygons is the ratio of the lengths of any two corresponding sides. C’ B’ A’ C B A It doesn’t matter the sides, they have the same ratio!

3. Other segments that have the same ratio as the sides: Page 36

4. Lets look at the perimeters… C’ B’ A’ C B A Remember: perimeter is the sum of all sides! Remember: Ratio of perimeters = ratio of the sides Page 36

5. Page 37

8. This means altitudes, medians, angle bisectors, etc… Ratio of altitudes = ratio of sides = ratio of perimeters
