Test Polygons and Quadrilaterals

Front

What is a parallelogram?

Back

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

Front

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

Back

The sum of the interior angles of a quadrilateral is 360 degrees.

Front

How do you find the measure of an interior angle of a regular polygon?

Back

Front

What is the relationship between the opposite angles of a parallelogram?

Back

The opposite angles of a parallelogram are equal.

Front

If one angle of a parallelogram is 70 degrees, what are the measures of the other angles?

Back

The opposite angle is also 70 degrees, and the adjacent angles are each 110 degrees.

Front

What is a regular polygon?

Back

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

Front

How do you determine the number of sides of a regular polygon given the measure of an interior angle?

Back

Front

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

Back

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

If ABCD is a parallelogram and angle A = 60 degrees, what is the measure of angle C?

Back

Angle C is also 60 degrees because opposite angles in a parallelogram are equal.
