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 ...

Learn about and revise angles, lines and multi-sided shapes and their properties with this BBC Bitesize GCSE Maths Edexcel study guide.

In a regular polygon all the angles are equal. Each interior angle is calculated by dividing the sum of the interior angles by the number of sides. Interior angle in a regular polygon = 180 (n 2) n ...

All the interior angles in a regular polygon are equal. The formula for calculating the size of an interior angle is: interior angle of a polygon = sum of interior angles ÷ number of sides.

It’s possible to work out the angles of polygons with more than 4 sides by cutting them up into triangles. This is a regular hexagon. It has 6 sides and it can be divided into 4 triangles, like ...

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.

All the interior angles in a regular polygon are equal. The formula for calculating the size of an interior angle is: interior angle of a polygon = sum of interior angles ÷ number of sides.
