Sum of exterior angles in a octagon

WebSince the sum of exterior angles of any polygon is always equal to 360°, we can divide by the number of sides of the regular polygon to get the measure of the individual angles. For example, for a pentagon, we have to divide 360° by 5: 360°÷5 = 72°. Each exterior angle in a regular pentagon measures 72°. In the following table, we can see ... Web8 Aug 2024 · Thus, for regular octagons, n = 8, so each interior angle is 180 × 6 8 = 135 o, and thus each exterior angle is 180 o − 135 o = 45 o. The sum of the angles of an n -gon is 180 ( n − 2). Plugging n = 8 here, we obtain 180 × 6 = 1080 ∘. Since the polygon is regular, an interior angle measures 1080 8 = 135 ∘.
