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

Front

What are the properties of opposite sides in a parallelogram?

Back

In a parallelogram, opposite sides are congruent (equal in length).

Front

What can be said about the consecutive angles in a parallelogram?

Back

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

Front

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

Back

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

Front

What is true about the diagonals of a parallelogram?

Back

The diagonals of a parallelogram bisect each other.

Front

If one angle of a parallelogram is 85°, what is the measure of the opposite angle?

Back

The opposite angle is also 85° because opposite angles in a parallelogram are congruent.

Front

If one angle of a parallelogram is 68°, what are the measures of the other three angles?

Back

The other angles are 112° (opposite angle) and 68° and 112° (consecutive angles).
