5.2 & 5.3 Practice #1 2021-2022

Front

What is a parallelogram?

Back

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

If one interior angle of a parallelogram is 30 degrees more than 9 times another angle, how do you express this relationship mathematically?

Back

Let the smaller angle be x. Then the larger angle can be expressed as 9x + 30.

Front

What is the relationship between opposite angles in a parallelogram?

Back

Opposite angles in a parallelogram are equal.

Front

How do you find the measure of an angle in a parallelogram if you know one angle?

Back

If you know one angle, you can find the opposite angle (which is equal) and the adjacent angles (which are supplementary to the known angle).

Front

What is the measure of the largest angle in a parallelogram if one angle is 165 degrees?

Back

The largest angle would be 165 degrees, as opposite angles are equal.

Front

If one angle of a parallelogram is 20 degrees more than another angle, how do you set up the equation?

Back

Let the smaller angle be x. Then the larger angle can be expressed as x + 20.

Front

What is the measure of the smaller angle if one angle is 0.50 times the measure of another angle?

Back

If the larger angle is x, then the smaller angle is 0.5x. If x = 120 degrees, then the smaller angle is 60 degrees.

Front

What is a key property of the sides of a parallelogram?

Back

In a parallelogram, opposite sides are equal in length.

Front

What is the relationship between the angles of a parallelogram?

Back

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