Interior and Exterior Polygon Angles

Front

What is the formula for finding the sum of the interior angles of a polygon?

Back

S = (n - 2) * 180° where n is the number of sides.

How do the interior and exterior angles of a polygon relate?

Back

They are supplementary.

Front

What is the measure of one exterior angle in a regular hexagon?

Back

60°

Front

If a polygon has 5 sides, what is the sum of its interior angles?

Back

540° (using S = (n - 2) * 180°, where n = 5).

Front

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

Back

135° (using the formula for interior angles: (n-2) * 180° / n).

Front

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

Back

72° (using the formula: 360° / n, where n = 5).

Front

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

Back

The sum increases by 180° for each additional side.

Front

What is the measure of an interior angle of a regular dodecagon (12-sided polygon)?

Back

150° (using the formula: (n-2) * 180° / n).

Front

If one interior angle of a polygon is 120°, what can you say about the other angles if the polygon is regular?

Back

Each interior angle is also 120°.
