Polygon Angles PRACTICE 12.3.24

Front

What is the formula to find the measure of one interior angle in a regular polygon?

Back

The formula is (n-2) * 180 / n, where n is the number of sides.

Front

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

Back

The sum of the interior angles can be calculated using the formula (n-2) * 180, where n is the number of sides.

Front

What is the measure of one interior angle in a regular 25-gon?

Back

165.6°

Front

What is the interior angle sum for a hexagon?

Back

720°

Front

If a polygon has 10 sides, what is the sum of its interior angles?

Back

1440°

Front

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

Back

135°

Front

How do you find the measure of an exterior angle of a regular polygon?

Back

The measure of an exterior angle is 360° / n, where n is the number of sides.

Front

What is the relationship between interior and exterior angles in a polygon?

Back

Interior and exterior angles are supplementary; their sum is 180°.

Front

If one interior angle of a polygon is 120°, how many sides does the polygon have?

Back

The polygon has 6 sides (hexagon).

Front

What is the measure of angle x if the interior angle is 105°?

Back

Angle x = 105°.
