6.4 Rectangle Properties

Front

What is a rectangle?

Back

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

Front

What are the properties of a rectangle?

Back

1. Opposite sides are equal in length. 2. All angles are 90 degrees. 3. Diagonals bisect each other and are equal in length.

Front

How do you find the area of a rectangle?

Back

Area = length × width.

Front

How do you find the perimeter of a rectangle?

Back

Perimeter = 2 × (length + width).

Front

What is the relationship between rectangles and parallelograms?

Back

All rectangles are parallelograms, but not all parallelograms are rectangles.

Front

What is the measurement of each angle in a rectangle?

Back

Each angle in a rectangle measures 90 degrees.

Front

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

Back

Area = 10 cm × 5 cm = 50 cm².

Front

If the length of a rectangle is 8 cm and the width is 3 cm, what is the perimeter?

Back

Perimeter = 2 × (8 cm + 3 cm) = 22 cm.

Front

What is the diagonal length of a rectangle with length 6 cm and width 8 cm?

Back

Diagonal = √(length² + width²) = √(6² + 8²) = √(36 + 64) = √100 = 10 cm.

Front

What is the formula for the diagonal of a rectangle?

Back

Diagonal = √(length² + width²).
