4.2 Flashcardizz. Properties of a Rectangle

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 are the properties of a rectangle?

Back

1. Opposite sides are equal in length. 2. All angles are 90 degrees. 3. Diagonals are equal in length. 4. Diagonals bisect each other.

Front

What is the measurement of each angle in a rectangle?

Back

90 degrees.

Front

Do the diagonals of a rectangle bisect each other?

Back

Yes, the diagonals of a rectangle bisect each other.

Front

Which of the following is not a property of all rectangles? (Options: both pairs of opposite sides have equal lengths, all angles are congruent, the diagonals are congruent, the diagonals are perpendicular)

Back

The diagonals are perpendicular.

Front

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

Back

Perimeter = 2(length + width) = 2(10 + 5) = 30 cm.

Front

If the length of a rectangle is 8 cm and the width is 4 cm, what is the area?

Back

Area = length × width = 8 × 4 = 32 cm².

Front

What is the formula for the area of a rectangle?

Back

Area = length × width.

Front

What is the formula for the perimeter of a rectangle?

Back

Perimeter = 2(length + width).

Front

How do you find the length of a rectangle if the area is 48 cm² and the width is 6 cm?

Back

Length = Area ÷ Width = 48 ÷ 6 = 8 cm.
