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. WebMay 17, 2024 · For any regular polygon, the measure and each interior angle is just the sum of the interior angles divided by the number of sides.
