Polygons and Interior Angle Sum

Front

What is a polygon?

Back

A polygon is a closed figure formed by a finite number of straight line segments that connect to form a closed chain or circuit.

Front

What is the formula to calculate the sum of interior angles of a polygon?

Back

The sum of the interior angles of a polygon with n sides is given by the formula: (n - 2) × 180°.

Front

What is the measure of one interior angle of a regular polygon?

Back

The measure of one interior angle of a regular polygon can be calculated using the formula: ((n - 2) × 180°) / n, where n is the number of sides.
