The interior angles of a pentagon
WebThe sum of the interior angles of a polygon of n sides can be calculated with the formula 180(n-2)°. It helps us in finding the total sum of all the angles of a polygon, whether it is a regular polygon or an irregular polygon. By using this formula, we can verify the angle sum property as well. The sum of all the interior angles of a triangle ... WebAn octagon has 8 sides, so: Exterior angle = 360° / n = 360° / 8 = 45° Interior Angle = 180° − Exterior Angle We know the Exterior angle = 360°/n, so: Interior Angle = 180° − 360°/n Which can be rearranged like this: Interior Angle = 180° − 360°/n = (n × 180° / n) − (2 × 180° / n) = (n−2) × 180°/n So we also have this:
