Rhombus, Square, Rectangle Properties

Front

What is a rhombus?

Back

A rhombus is a quadrilateral with all four sides of equal length and opposite angles that are equal.

Front

What are the properties of a square?

Back

A square is a quadrilateral with all sides equal, all angles equal to 90 degrees, and diagonals that bisect each other at right angles.

Front

What defines a rectangle?

Back

A rectangle is a quadrilateral with opposite sides equal and all angles equal to 90 degrees.

Front

How do you find the area of a rectangle?

Back

Area = length × width.

Front

What is the relationship between the diagonals of a rhombus?

Back

The diagonals of a rhombus bisect each other at right angles.

Front

What is the formula for the perimeter of a square?

Back

Perimeter = 4 × side length.

Front

How do you calculate the length of the diagonal in a rectangle?

Back

Diagonal = √(length² + width²).

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 two angles of a rhombus are 62 degrees, what are the other two angles?

Back

The other two angles are 118 degrees each, since opposite angles are equal and adjacent angles are supplementary.

Front

What is the relationship between the sides of a square and its diagonal?

Back

The diagonal of a square is √2 times the length of a side.
