WebApr 24, 2024 · To the contrary, a concave polygon has one or more of its interior angles greater than 180°. A polygon is called regular when its sides are equal and also its interior angles are equal. Having only the sides equal is not adequate to guarantee that the interior angles are also equal. WebOctagons have 8 sides so again, we need to adjust the formula accordingly: sum of internal angles = (8 - 2) x 180°. 1080° = 6 x 180°. In a regular octagon, one angle would be … 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. 7 goldfish feng shui
