Front

What is a parallelogram?

Back

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

Front

How do you find the missing side of a parallelogram?

Back

To find the missing side of a parallelogram, use the property that opposite sides are equal in length.

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 the relationship between the angles in a parallelogram?

Back

In a parallelogram, opposite angles are equal, and adjacent angles are supplementary (add up to 180 degrees).

Front

How do you calculate the measure of a missing angle in a parallelogram?

Back

To calculate a missing angle, use the fact that the sum of the angles in a parallelogram is 360 degrees and that opposite angles are equal.

Front

What is the formula for the area of a parallelogram?

Back

The area of a parallelogram is calculated using the formula: Area = base × height.

Front

What is the definition of supplementary angles?

Back

Supplementary angles are two angles whose measures add up to 180 degrees.

Front

What is the definition of complementary angles?

Back

Complementary angles are two angles whose measures add up to 90 degrees.

Front

If one angle of a parallelogram is 90 degrees, what can be said about the other angles?

Back

If one angle is 90 degrees, then the opposite angle is also 90 degrees, and the adjacent angles are 90 degrees each, making it a rectangle.

Front

How do you solve for x in an equation?

Back

To solve for x, isolate x on one side of the equation using inverse operations.
