Rhombuses, Rectangles, and Squares

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 are the properties of a rectangle?

Back

A rectangle is a quadrilateral with opposite sides that are equal in length and all angles measuring 90 degrees.

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 (sum to 180 degrees).

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

What is the measure of each angle in a square?

Back

Each angle in a square measures 90 degrees.

Front

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

Back

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

Front

What is the sum of the interior angles of a quadrilateral?

Back

The sum of the interior angles of a quadrilateral is 360 degrees.

Front

What is the measure of each angle in a rhombus if one angle measures 60 degrees?

Back

If one angle in a rhombus measures 60 degrees, the opposite angle also measures 60 degrees, and the other two angles measure 120 degrees each.

Front

How do you determine if a quadrilateral is a square?

Back

A quadrilateral is a square if all four sides are equal in length and all angles are 90 degrees.

Front

What is the formula for the area of a rectangle?

Back

The area of a rectangle is calculated using the formula: Area = length × width.
