Properties of Rectangles, Rhombi, and Squares

How do you find the length of the diagonals in a rectangle?

• d = length + width

• d = length - width

• d = √(length² + width²)

• d = length × width

What is the area formula for a square?

• Area = side × 4

• Area = side²

• Area = 2 × side

• Area = side + side

What is a square?

• A shape with four equal sides and four right angles.

• A shape with unequal sides and angles.

• A shape with three sides and three angles.

• A shape that can be any length and width.

What is the perimeter formula for a rhombus?

• Perimeter = 2 × (length + width)

• Perimeter = 4 × side length

• Perimeter = side length × 4

• Perimeter = 2 × side length

What is the measure of angle 1 if it is 72 degrees?

• 60 degrees

• 72 degrees

• 90 degrees

• 45 degrees

What is the relationship between the angles of a rectangle?

• Each angle is 90 degrees, and opposite angles are equal.

• All angles are acute angles.

• The angles are all different sizes.

• Each angle is 180 degrees.

How do the diagonals of a rhombus behave?

• They are equal in length and bisect each other at 45 degrees.

• They bisect each other at right angles (90 degrees).

• They do not bisect each other and are of different lengths.

• They are perpendicular but do not bisect each other.

If m∠CDA = 9x + 3 and m∠EDA = 6x + 15, what is the value of x?

• 5

What is a rhombus?

• A quadrilateral with all four sides of equal length and opposite angles that are equal.

• A polygon with three sides and three angles.

• A four-sided figure with only one pair of parallel sides.

• A shape that has all right angles and equal sides.
