Polygons: Interior & Exterior Angle Rules

Front

What is a polygon?

Back

A polygon is a closed two-dimensional shape formed by a finite number of straight line segments connected end to end.

Front

What are the interior angles of a polygon?

Back

Interior angles are the angles formed inside a polygon by its sides.

Front

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°, where n is the number of sides.

Front

What is the exterior angle of a polygon?

Back

An exterior angle is formed by one side of the polygon and the extension of an adjacent side.

Front

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

Back

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

Front

What is the relationship between interior and exterior angles?

Back

Each interior angle and its corresponding exterior angle are supplementary, meaning they add up to 180°.

Front

What is a regular polygon?

Back

A regular polygon is a polygon with all sides and angles equal.

Front

What is an irregular polygon?

Back

An irregular polygon is a polygon that does not have all sides and angles equal.

Front

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

Back

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

Front

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

Back

To find the measure of each exterior angle in a regular polygon, use the formula: 360° / n, where n is the number of sides.
