Web20 Jan 2024 · Then multiply the exterior angles by 8 to find the sum of all exterior angles. The sum of the interior angles is calculated by 180° times the number of sides (n) subtract 2. An octagon has 8 sides, so n = 8. 180°(n - 2) Substitute (replace) n with 8 = 180°(8 - 2) Subtract inside the brackets = 180°(6) Multiply = 1080° Sum of all interior ... WebThis confirms that the exterior angles, taken one per vertex, add to 360° The sum of exterior angles - watch out! In most geometry textbooks they say flatly that the exterior angles of a polygon add to 360° This is only true if: You take only one per vertex, and Take all the angles that point in the same direction around the polygon. WebFind the sum of the measures of the interior angles of an octagon. Solution: An octagon has 8 sides. So, n = 8 . Substitute 8 for n in the formula. The sum of the measures of the interior angles of an octagon = ( 8 − 2) 180 ° . = 6 × 180 ° = 1080 °. The sum of the measures of the interior angles of an octagon is 1080 ° . randall bowie knife for sale
