Front

What is the sum of the interior angles of a hexagon?

Back

The sum of the interior angles of a hexagon is 720 degrees.

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 an exterior angle of a polygon?

Back

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

Front

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

Back

The interior angle and the exterior angle at each vertex of a polygon are supplementary, meaning they add up to 180 degrees.

Front

If the interior angles of a polygon add up to 720 degrees, how many sides does the polygon have?

Back

The polygon has 6 sides (it is a hexagon).

Front

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

Back

Each interior angle of a regular hexagon measures 120 degrees.

Front

What is the formula to find the measure of an exterior angle of a regular polygon?

Back

The measure of an exterior angle of a regular polygon can be found using the formula: 360° / n, where n is the number of sides.

Front

If one exterior angle of a polygon is 25.7°, what is the number of sides of the polygon?

Back

The polygon has 14 sides, calculated as 360° / 25.7°.

Front

What is the value of 'b' if the options are b = 360, b = 34, b = 340, b = 180?

Back

b = 34.

Front

How do you find the measure of an angle in a triangle if two angles are known?

Back

You can find the measure of the third angle by subtracting the sum of the known angles from 180°.
