Front

What is a rectangle?

Back

A rectangle is a quadrilateral with four right angles and opposite sides that are equal in length.

Front

What is a rhombus?

Back

A rhombus is a quadrilateral with all four sides of equal length and opposite angles that are equal.

Front

What is a square?

Front

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

Back

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

Front

If one angle of a rhombus is 37 degrees, what are the measures of the other angles?

Back

The opposite angle is also 37 degrees, and the adjacent angles are 143 degrees each.

Front

What is the relationship between the diagonals of a rhombus?

Back

The diagonals of a rhombus bisect each other at right angles.

Front

What is the relationship between the diagonals of a rectangle?

Back

The diagonals of a rectangle are equal in length and bisect each other.

Front

If a rectangle has a length of 10 cm and a width of 5 cm, what is its area?

Back

The area of the rectangle is 50 cm² (Area = length × width).
