Interior and Exterior Angles of Polygons

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.

Front

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

Back

Each interior angle = (n - 2) × 180° / n, where n is the number of sides.

Front

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

Back

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

Front

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

Back

Interior angle + Exterior angle = 180°.

Front

What is the sum of the angle measures in a triangle?

Back

The sum of the angle measures in a triangle is 180°.

Front

What is a polygon?

Back

A polygon is a closed figure formed by a finite number of straight line segments.

Front

What is a regular polygon?

Back

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

Front

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

Back

Each exterior angle = 360° / n, where n is the number of sides.

Front

What is the difference between convex and concave polygons?

Back

Convex polygons have all interior angles less than 180°, while concave polygons have at least one interior angle greater than 180°.

Front

What is a quadrilateral?

Back

A quadrilateral is a polygon with four sides.
