Rhombuses, Rectangles, and Squares

Front

What is a rhombus?

Back

A rhombus is a quadrilateral with all four sides of equal length. Opposite angles are equal, and adjacent angles are supplementary.

Front

What is a rectangle?

Back

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

Front

What is a square?

Back

A square is a special type of rectangle and rhombus where all four sides are equal in length and all angles are 90 degrees.

Front

How do you classify a square?

Back

A square is classified as both a rectangle (because it has right angles) and a rhombus (because it has equal sides).

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 formula for the area of a rectangle?

Back

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

Front

What is the formula for the area of a square?

Back

The area of a square is calculated using the formula: Area = side².

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 the sides of a square are 5 cm, what is its perimeter?

Back

The perimeter of a square is calculated using the formula: Perimeter = 4 × side. So, Perimeter = 4 × 5 cm = 20 cm.

Front

If the length of a rectangle is 10 cm and the width is 4 cm, what is its area?

Back

Area = length × width = 10 cm × 4 cm = 40 cm².
