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.

By definition, the interior angles of a regular polygon are all equal, and since we know the number of angles (n) and their sum (180 (n − 2)), we can just divide to compute the measure of each ...
