Each interior angle
WebEach interior angle of a regular nonagon measures 140°. This can be calculated using the formula for the interior angles of a regular polygon. Interior angle of a regular polygon =\(\frac{180n–360} {n}\), where n = the number of sides of the polygon. In a nonagon, n = 9. After substituting this value of 'n' in the formula, we get \(\begin ... WebSum of the Interior Angles of Decagon. To find the sum of the interior angles of a decagon, first, divide it into triangles. There are eight triangles in a regular decagon. We know that the sum of the angles in each triangle is 180°. Thus, 180° × 8 = 1440°. Therefore, the sum of all the interior angles of a decagon is 1440°.
