How do you calculate the sum of the interior angles of a polygon?

Back

The sum of the interior angles of a polygon can be calculated using the formula: (n - 2) × 180 degrees, where n is the number of sides.

What is the measure of each interior angle in a regular hexagon?

Back

In a regular hexagon, each interior angle measures 120 degrees.

Front

What is the measure of each exterior angle in a regular polygon?

Back

The measure of each exterior angle in a regular polygon can be calculated using the formula: 360 degrees / n, where n is the number of sides.
