Unit 5 Review

Front

What is a parallelogram?

Back

A parallelogram is a four-sided figure (quadrilateral) where opposite sides are equal in length and parallel.

Front

What is the measure of angle R in parallelogram PQRS if angle P is 124 degrees?

Back

Angle R measures 56 degrees.

Front

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

Back

The formula is \( \frac{(n-2) \times 180}{n} \), where n is the number of sides.

Front

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

Back

Each interior angle of a regular pentagon measures 108 degrees.

Front

What is true for all parallelograms?

Back

Opposite sides are equal and parallel.

Front

What are the properties of a square?

Back

A square has four congruent sides, four congruent angles, and is a regular polygon.

Front

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

Back

Each exterior angle of a regular octagon measures 45 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 is given by the formula \( (n-2) \times 180 \) degrees, where n is the number of sides.

Front

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

Back

The interior and exterior angles of a polygon are supplementary, meaning they add up to 180 degrees.

Front

What is a regular polygon?

Back

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