**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**
