1. Honors Geometry Section 5.5 Areas of Regular Polygons

2. Recall that a regular polygon is
a polygon that is both equilateral and equiangular.

3. The center of a regular polygon is A radius of a regular polygon is

4. An apothem of a regular polygon is a segment from the center perpendicular to a side. An apothem also _______the side of a regular polygon.
bisects

5. The area of any regular n-gon can be found by dividing the regular polygon into n congruent triangles. This is done by drawing the radii of the regular polygon. A reg polygon = area of 1 triangle times the number of triangles.

6. So the formula for the area of a regular polygon is

7. Examples: Find the (exact) area of each regular polygon.

8. Examples: Find the (exact) area of each regular polygon.

9. Examples: Find the (exact) area of each regular polygon.

10. Examples: Find the (exact) area of each regular polygon.
