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 diagonals of a rectangle?

Back

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

Front

How do you find the area of a rectangle?

Back

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

Front

What is the formula for the perimeter of a rectangle?

Back

The perimeter of a rectangle is calculated using the formula: Perimeter = 2(length + width).

Front

What is the relationship between the opposite sides of a rectangle?

Back

In a rectangle, opposite sides are equal in length.

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 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 doubled, how does it affect the area?

Back

If the length is doubled, the area also doubles, assuming the width remains the same.

Front

What is the definition of a right angle?

Back

A right angle is an angle that measures exactly 90 degrees.

Front

How do you identify the angles formed by intersecting lines in a rectangle?

Back

The angles formed by intersecting lines in a rectangle can be identified using angle notation, such as ∠KLM.
