Properties and Formulas of Rhombuses

The video tutorial explains how to calculate the area and perimeter of a rhombus. It begins by describing the properties of a rhombus, noting that all sides are equal. The area is calculated using the formula base times height, where the base is the bottom side and the height is the vertical distance. The perimeter is found by adding the lengths of all four sides, which can also be calculated by multiplying one side by four.

What is the first step in solving the area and perimeter of a rhombus?

• Identify the length of the sides

• Calculate the diagonal lengths

• Find the angles of the rhombus

• Determine the type of rhombus

How is a rhombus similar to a square?

• Both have equal angles

• Both have equal perimeters

• Both have equal sides

• Both have equal diagonals

What is the relationship between the sides of a rhombus?

• No sides are equal

• Adjacent sides are equal

• Opposite sides are equal

• All sides are equal

Which of the following is NOT a property of a rhombus?

• Diagonals are equal

• Diagonals bisect each other

• All sides are equal

• Opposite angles are equal

What formula is used to find the area of a rhombus?

• Side times side

• Base times height

• Length times width

• Diagonal times diagonal

In a rhombus, what is the base?

• The longest side

• The side it sits on

• The height

• The diagonal

What is the height of a rhombus?

• The diagonal

• The base

• The vertical distance

• The slant height

Which of the following is true about the height of a rhombus?

• It is equal to the diagonal

• It is the slant height

• It is equal to the base

• It is perpendicular to the base

How do you calculate the area of a rhombus with a base of 5 and height of 4?

• 5 x 5

• 5 x 4

• 5 + 4

• 4 x 4

If the base of a rhombus is 5 cm and the height is 4 cm, what is the area?

• 15 square cm

• 10 square cm

• 20 square cm

• 25 square cm
