Interior/Exterior Angles of Polygons

Front

What is the formula to calculate the sum of the 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 degrees.

Front

How many sides does a hexagon have?

Back

A hexagon has 6 sides.

Front

What is the sum of the measures of the interior angles of a triangle?

Back

The sum of the measures of the interior angles of a triangle is 180 degrees.

Front

What is the sum of the measures of the interior angles of a quadrilateral?

Back

The sum of the measures of the interior angles of a quadrilateral is 360 degrees.

Front

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

Back

To find the measure of one interior angle of a regular polygon, use the formula: \( \frac{(n - 2) \times 180}{n} \) degrees, where n is the number of sides.

Front

What is the measure of each interior angle of a regular pentagon?

Back

Each interior angle of a regular pentagon measures 108 degrees.

Front

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

Back

The interior and exterior angles of a polygon are supplementary, meaning they add up to 180 degrees.

Front

What is the sum of the measures of the exterior angles of any polygon?

Back

The sum of the measures of the exterior angles of any polygon is always 360 degrees.

Front

If one interior angle of a polygon is 120 degrees, what is the measure of its corresponding exterior angle?

Back

The corresponding exterior angle is 60 degrees, since interior and exterior angles are supplementary.
