WebbSince, for the hexagon we have n = 6. d = 180 n - 2 n ⇒ d = 180 6 - 2 2 ⇒ d = 180 × 4 2 ∴ d = 120. So, the value of interior angle is 120 °. Now, subtract the obtained value from 180 ° to get the value of exterior angles. So, the exterior angle of a regular hexagon will be: 180 ° - 120 ° = 60 °. Hence, the required solution is 60 °. Webb7. 900°. Octagon. 8. 1080°. The measure of each internal angle in a regular polygon is found by dividing the total sum of the angles by the number of sides of the polygon.
