Interior Angles of Polygons

Front

What is the formula to find 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°, where n is the number of sides.

How do you find the measure of one interior angle in a regular polygon?

Back

To find the measure of one interior angle in a regular polygon, use the formula: (n - 2) × 180° / n, where n is the number of sides.

What is the interior angle sum of a hexagon?

Back

The interior angle sum of a hexagon is 720°.

Front

If a polygon has 8 sides, what is the sum of its interior angles?

Back

The sum of the interior angles of an octagon (8 sides) is (8 - 2) × 180° = 1080°.

Front

What is the measure of one interior angle in a regular octagon?

Back

The measure of one interior angle in a regular octagon is (8 - 2) × 180° / 8 = 135°.

Front

What is the relationship between the number of sides and the interior angle sum of a polygon?

Back

As the number of sides increases, the sum of the interior angles increases according to the formula (n - 2) × 180°.
