Similar Polygons - Finding Areas using scale factors


1. Guided Practice Notes

2. Your turn practice (students)

3. Class Exercise

4. Detailed Solution Key to the class exercise

Key concept:

Theorem (similar polygons):

1) Ratio of the perimeters = (a/b)

2) Ratio of the areas = (a/b)^2

Scale factor = a/b
