Parallelograms, Rectangles, Rhombuses and Squares 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 is the sum of the interior angles of a quadrilateral?

Back

The sum of all four angles in a quadrilateral is 360 degrees.

Front

What are the properties of a rectangle?

Back

A rectangle is a parallelogram with four right angles (90 degrees) and opposite sides that are equal in length.

Front

What is a rhombus?

Back

A rhombus is a parallelogram with all four sides of equal length.

Front

What is a square?

Back

A square is a special type of rectangle and rhombus that has all sides equal and all angles equal to 90 degrees.

Front

If angle A and angle B are consecutive angles in a parallelogram, what is their relationship?

Back

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

Front

How do you find the length of a diagonal in a rectangle?

Back

The length of a diagonal in a rectangle can be found using the Pythagorean theorem: d = √(length² + width²).

Front

What is the formula for the area of a rectangle?

Back

The area of a rectangle is calculated as Area = length × width.

Front

What is the formula for the area of a rhombus?

Back

The area of a rhombus can be calculated using the formula: Area = (diagonal1 × diagonal2) / 2.

Front

If one angle of a rectangle is 58 degrees, what is the measure of the adjacent angle?

Back

The adjacent angle is 32 degrees, since adjacent angles in a rectangle are complementary.
