Exterior Angle Practice

Front

What is an exterior angle in a polygon?

Back

An exterior angle is formed by one side of a polygon and the extension of an adjacent side. It is equal to the sum of the two opposite interior angles.

Front

How do you calculate the measure of an exterior angle of a triangle?

Back

The measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles.

Front

What is the relationship between the exterior angle and the interior angle of a triangle?

Back

The exterior angle is equal to the sum of the two opposite interior angles, and the interior angle and exterior angle are supplementary (they add up to 180 degrees).

Front

If one interior angle of a triangle is 50 degrees, what is the measure of the corresponding exterior angle?

Back

The corresponding exterior angle would be 130 degrees, since 180 - 50 = 130.

Front

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

Back

The sum of the exterior angles of any polygon is always 360 degrees, regardless of the number of sides.

Front

How do you find the measure of an exterior angle if you know the interior angles of a triangle?

Back

To find the measure of an exterior angle, add the measures of the two non-adjacent interior angles.

Front

What is the formula for calculating the measure of each exterior angle of a regular polygon?

Back

The measure of each exterior angle of a regular polygon can be calculated using the formula: 360 degrees divided by the number of sides (n).

Front

If a regular polygon has 8 sides, what is the measure of each exterior angle?

Back

Each exterior angle of a regular octagon (8 sides) is 45 degrees, since 360 degrees / 8 = 45 degrees.

Front

What is the difference between an interior angle and an exterior angle?

Back

An interior angle is formed inside the polygon, while an exterior angle is formed outside the polygon by extending one of its sides.

Front

How can you use exterior angles to solve for unknown angles in a triangle?

Back

You can use the property that the exterior angle is equal to the sum of the two opposite interior angles to set up equations and solve for unknown angles.
