This video tutorial explains how to calculate the area of a rhombus or kite using the formula involving diagonals. It begins by defining the properties of rhombuses and kites, followed by a detailed explanation of the area formula. The video includes four examples demonstrating the application of the formula, addressing unit conversion and diagonal identification. Each example illustrates the step-by-step process of calculating the area, ensuring a comprehensive understanding of the concept.

• A quadrilateral with all sides of different lengths

• A quadrilateral with two pairs of equal sides

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

• All sides are equal

• Opposite angles are equal

• Diagonals bisect each other at right angles

• All angles are right angles

What is the relationship between the diagonals in a rhombus?

• They are parallel

• They are equal in length

• They bisect each other at right angles

• One diagonal bisects the other

What is a key characteristic of a kite?

• All sides are of equal length

• Two pairs of sides are equal in length

• It has one pair of parallel sides

• All angles are right angles

Which of the following is NOT a characteristic of a kite?

• Two pairs of adjacent sides are equal

• Diagonals intersect at right angles

• All sides are equal

• One diagonal bisects the other

What is the relationship between the diagonals in a kite?

• They bisect each other at right angles

• They are equal in length

• One diagonal bisects the other

• They are parallel

How is the area of a kite or rhombus calculated?

• By squaring the length of one side

• By multiplying the lengths of all sides

• By adding the lengths of the diagonals

• By multiplying half of one diagonal by the other diagonal

What is the formula for the area of a kite or rhombus?

• Area = 1/2 × diagonal1 × diagonal2

• Area = base × height
