WebWe can learn a lot about regular polygons by breaking them into triangles like this: Notice that: the "base" of the triangle is one side of the polygon. the "height" of the triangle is the "Apothem" of the polygon. Now, the area of a triangle is half of the base times height, so: Area of one triangle = base × height / 2 = side × apothem / 2. WebDec 24, 2015 · The formula for calculating the sum of the interior angles of a regular polygon is: (n - 2) × 180°. Where n is number of sides. sum of angles = (n - 2) × 180. …
