Ch 6 - Properties of Rectangles, Rhombuses and Squares

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 rhombus?

Back

A rhombus is a quadrilateral with all four sides of equal length, opposite angles that are equal, and diagonals that bisect each other at right angles.

Front

What defines a square?

Back

A square is a quadrilateral that has all sides equal in length and all angles equal to 90 degrees. It is a special type of rectangle and rhombus.

Front

How do you find the perimeter of a rectangle?

Back

The perimeter of a rectangle is found using the formula P = 2(length + width).

Front

What is the area of a rectangle?

Back

The area of a rectangle is calculated using the formula A = length × width.

Front

If QS = 4x - 7 and RT = 2x + 11, how do you find x?

Back

Set the two expressions equal to each other: 4x - 7 = 2x + 11. Solve for x to find x = 9.

Front

What is the relationship between the diagonals of a rectangle?

Back

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

Front

What is the measure of the angles in a rhombus?

Back

The opposite angles in a rhombus are equal, and the adjacent angles are supplementary (add up to 180 degrees).

Front

How can you classify a quadrilateral with four equal sides and opposite angles that are equal?

Back

It can be classified as a rhombus.

Front

What is the difference between a rectangle and a rhombus?

Back

A rectangle has four right angles, while a rhombus has all sides equal but does not require right angles.
