3. Learning Target I can find the area of a regular polygon

4. What is a regular polygon, again?

5. The center of a regular polygon is the center of a circle circumscribed about the polygon. The radius is the distance from the center to the vertex Apothem: the perpendicular distance from the center to a side

6. Finding Angle Measures of Regular Polygons

7. Do 4-6

8. Do 1-3

9. Area of a regular polygon A = ½ ap Where a is the apothem and p is the perimeter of the polygon

10. Do 10-12

11. Show 7, try 8 and 9

12. RECAP – Can you find missing angle measures of a regular polygon? – Can you use properties of 30-60-90 and 45-45-90 triangles to find a missing apothem or radius? – Can you find the area of a regular polygon using an apothem and side length?
