First-half of UNIT 6 Review

Front

What is the formula to find the measure of each interior angle of a regular polygon?

Back

The measure of each interior angle of a regular polygon can be found using the formula: (n-2) * 180° / n, where n is the number of sides.

Front

How many sides does a regular polygon have if each interior angle measures 135 degrees?

Back

8 sides.

Front

What is a rectangle?

Back

A rectangle is a quadrilateral with four right angles (90 degrees) and opposite sides that are equal in length.

Front

True or False: In a rectangle, all angles are congruent.

Back

True.

Front

What is the sum of the interior angles of a polygon with n sides?

Back

The sum of the interior angles of a polygon with n sides is (n-2) * 180°.

Front

How many angles are in a nonagon?

Back

9 angles.

Front

What is the relationship between consecutive angles in a rectangle?

Back

Consecutive angles in a rectangle are supplementary, meaning they add up to 180 degrees.

Front

Which statement is NOT true about angles in a rectangle?

Back

Diagonals bisect the angles.

Front

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

Back

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

Front

If a polygon has 10 sides, how many interior angles does it have?

Back

10 interior angles.
