WebJan 21, 2024 · KEY FACT: To calculate the sums of the interior angles of any convex n-gon, use the general formula: 180Degrees* (n-2). ( where n represents the number of sides of the polygon) The chart below … WebTherefore, the measure of the interior angle of a 24-gon is 165 degrees. 4. To find the number of sides of a polygon when given the sum of the interior angles, we can use the formula: Sum of interior angles = (n-2) x 180 degrees. where n is the number of sides of the polygon. Rearranging the formula, we get: WebJul 8, 2024 · Angle Q is an interior angle of quadrilateral QUAD. Exterior angle: An exterior angle of a polygon is an angle outside the polygon formed by one of its sides and the extension of an adjacent side. The sum of the measures of the interior angles of a polygon with n sides is ( n – 2)180. The measure of each interior angle of an equiangular n ... 7 great apps for remote workers
