2. g-co.4.13 ; g-srt.3.8 Essential Question:
How are can I find the area of a regular polygon?
Objective:
Students will be able to find area of regular polygons.

3. parts center radius: (AB or AD)
apothem: (AC) distance from the center to any side of the polygon
central ∡: (∡BAD) an ∡ formed by radii drawn to two consecutive vertices of the polygon

4. area of a regular polygon
The area of a regular polygon is ½ the product of the apothem & the perimeter.

5. find area & perimeter

6. * Find central ∡ & use trig ratios to get lengths.
