Lesson 9.3-Properties of Rectangles, Rhombuses and Squares

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 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 and all angles are 90 degrees.

Front

What are the properties of a parallelogram?

Back

In a parallelogram, opposite sides are equal, opposite angles are equal, and the diagonals bisect each other.

Front

How do you find the value of x in a rectangle when given side lengths?

Back

Set the expressions for the lengths equal to each other and solve for x.

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

What is the relationship between the diagonals of a rhombus?

Back

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

Front

If one angle of a rhombus is 38 degrees, what are the measures of the other angles?

Back

The opposite angles are also 38 degrees, and the other two angles are 142 degrees each.

Front

What is the formula for the area of a rectangle?

Back

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

Front

What is the formula for the area of a rhombus?

Back

The area of a rhombus can be calculated using the formula: Area = (diagonal1 × diagonal2) / 2.
