Find the Area of ANY Regular Polygon Given its Radius
In this video, I'll be showing you how to find the area of any regular polygon using a simple and effective method.
First, we'll then cut up the polygon into a bunch of congruent isosceles triangles using the center of the polygon as the vertex of each triangle.
After that, we'll use the triangle area formula of 1/2 ab sin(c) to find the area of one triangle. This formula uses the length of the base and the height of the triangle, as well as the angle between the base and the height. I'll explain how to calculate each of these values in detail.
Finally, we'll multiply the area of one triangle by the number of triangles to find the area of the regular polygon. This method works for any regular polygon, regardless of the number of sides.
Whether you're a student learning geometry or just curious about how to calculate the area of a regular polygon, this video is for you. So grab a pen and paper, and let's get started!
