Unit 5 Review #1: Quadrilaterals (solving) Used for TEST review

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

What are the properties of a rhombus?

Back

A rhombus is a type of parallelogram where all four sides are of equal length, opposite angles are equal, and adjacent angles are supplementary.

Front

In a parallelogram, what is true about opposite angles?

Back

In a parallelogram, opposite angles are equal.

Front

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

Back

To find the measure of an angle in a parallelogram, use the property that adjacent angles are supplementary (sum to 180 degrees).

Front

What is the relationship between the diagonals of a parallelogram?

Back

The diagonals of a parallelogram bisect each other.

Front

If one angle of a parallelogram is 58 degrees, what is the measure of the opposite angle?

Back

The opposite angle is also 58 degrees.

Front

In parallelogram ABCD, if angle A is 60 degrees, what is the measure of angle B?

Back

Angle B is 120 degrees because adjacent angles are supplementary.

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

If the base of a parallelogram is 10 units and the height is 5 units, what is the area?

Back

The area is 50 square units (10 × 5 = 50).

Front

In rhombus DOGS, if one diagonal measures 10 units, what can be said about the other diagonal?

Back

The diagonals of a rhombus bisect each other at right angles, but their lengths can vary.
