An exterior angle of a regular polygon can be found by dividing 360° by the number of sides (𝒏). Eg, for an eight-sided shape (octagon), divide 360° by 8 to find the size of an exterior angle ...

Polygons can be regular or irregular. If the angles are all equal and all the sides are equal length it is a regular polygon. To find the sum of interior angles in a polygon divide the polygon ...

The formula for finding the sum of the interior angles in any polygon is: Sum of interior angles = two less than the number of sides x 180° In algebra this is Sum of interior angles = 180 (n – 2) ...

The sum of the angles in a triangle is 180°. To find the sum of the interior angles of a polygon, multiply the number of triangles in the polygon by 180°.

Learn more about how angles in an 𝒏-sided polygon add to 180° × (𝒏 – 2) with this BBC Bitesize Maths article. For students between the ages of 11 and 14.

The sum of exterior angles of a polygon is 360°. The formula for calculating the size of an exterior angle is: exterior angle of a polygon = 360 ÷ number of sides.
