Front

What is a polygon?

Back

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

Front

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

Back

Divide the sum of the interior angles by the number of sides: (n-2) * 180 / n.

Front

What is a regular polygon?

Back

A regular polygon is a polygon with all sides and all 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 many sides does a hexagon have?

Back

A hexagon has 6 sides.

Front

Calculate the sum of the interior angles of a pentagon.

Back

The sum is 540 degrees, calculated as (5-2) * 180.

Front

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

Back

Each interior angle measures 135 degrees, calculated as (8-2) * 180 / 8.

Front

How many degrees are in the sum of the interior angles of a decagon?

Back

The sum is 1440 degrees, calculated as (10-2) * 180.

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.
