Answer:

Properties

The properties of polygons are based on its sides and angles.

The sum of all the interior angles of an n-sided polygon is (n – 2) × 180°.

The number of diagonals in a polygon with n sides = n(n – 3)/2

The number of triangles formed by joining the diagonals from one corner of a polygon = n – 2

The measure of each interior angle of n-sided regular polygon = [(n – 2) × 180°]/n

The measure of each exterior angle of an n-sided regular polygon = 360°/n
