How to calculate angles in a polygon
WebAll central angles would add up to 360° (a full circle), so the measure of the central angle is 360 divided by the number of sides. Or, as a formula: central angle = 360 n degrees where n is the number of sides The measure of the central angle thus depends only on the number of sides. WebTo find the measure of one interior angle, we divide the result by n. For example, let's consider a 3-sided regular polygon, that is, an equilateral triangle. We use the formula, and substitute n with 3. We get the result to be 180. Now, if we divide it by n, that is, 3, we get 60, which is the measure of an interior angle of a triangle.

The other lengths would be L1/2, L2, L3 but I'm not sure of its usefulness. I know the sum of interior angles is 540 degrees for the pentagon and 360 for the the other one.
Web13 jun. 2024 · In a regular pentagon, each exterior angle is 72°. This is because each angle is the same size and 360° ÷ 5 = 72°. Exterior angles of all polygons always add up to 360°. We can see the 5 exterior angles of a regular pentagon marked below. Exterior angles add up to 360° because each polygon can be shrunk down until it forms a point. WebSo if we know that a pentagon adds up to 540 degrees, we can figure out how many degrees any sided polygon adds up to. Hexagon has 6, so we take 540+180=720. A …
