Rectangles

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 the angles in a rectangle?

Back

All angles in a rectangle are congruent, meaning each angle measures 90 degrees.

Front

What is the relationship between the sides of a rectangle?

Back

Opposite sides of a rectangle are parallel and congruent, while consecutive sides are perpendicular.

Front

Are all sides of a rectangle congruent?

Back

No, only opposite sides are congruent; consecutive sides can be of different lengths.

Front

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

Back

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

Front

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

Back

The perimeter P of a rectangle is given by P = 2(length + width). So, P = 2(10 + 5) = 30 units.

Front

If the length of a rectangle is 8 units and the width is 3 units, what is the area?

Back

The area A of a rectangle is given by A = length × width. So, A = 8 × 3 = 24 square units.

Front

In a rectangle, what can be said about the diagonals?

Back

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

Front

What is the relationship between consecutive angles in a rectangle?

Back

Consecutive angles in a rectangle are supplementary, meaning they add up to 180 degrees.

Front

If one diagonal of a rectangle measures 10 units, what is the length of the other diagonal?

Back

In a rectangle, both diagonals are equal, so the other diagonal also measures 10 units.
