2. How do we get the area of regular polygons? A regular polygon is equiangular and equilateral. A circle circumscribes the polygon. Thus, a regular polygon has a center. Radii will divide the polygon into congruent triangles.

3. How do we get the area of regular polygons? Let’s say that each side is s. Determine the area of 1 triangle. APOTHEM: Perpendicular segment from center of regular polygon to side of polygon

4. How do we get the area of regular polygons? Area of the polygon:
