Rhombuses, Rectangles, and Squares 1

Front

What is a rhombus?

Back

A rhombus is a type of polygon that is a quadrilateral (four sides) with all 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

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

Back

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

Front

If a square has a side length of 4 cm, what is its area?

Back

The area of a square is calculated as side length squared. Therefore, area = 4 cm x 4 cm = 16 cm².

Front

What is the relationship between the diagonals of a rhombus?

Back

The diagonals of a rhombus bisect each other at right angles and are not necessarily equal in length.

Front

How do you find the perimeter of a rectangle?

Back

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

Front

What is the formula for the area of a rectangle?

Back

The area of a rectangle is calculated as: Area = length x width.

Front

What is the measure of each angle in a square?

Back

Each angle in a square measures 90 degrees.

Front

If the diagonals of a square are 10 cm long, what is the length of each side?

Back

The length of each side of the square can be found using the formula: side = diagonal / √2. Therefore, side = 10 cm / √2 ≈ 7.07 cm.
