Understanding the Area of a Kite

This video tutorial focuses on calculating the area of a kite using different methods. It begins with a basic example using the formula for kite area, followed by a more complex example involving the Pythagorean theorem to find missing side lengths. The final example incorporates angles and trigonometry to determine the kite's area. Each example builds on the previous one, providing a comprehensive understanding of the topic.

What is the formula for calculating the area of a kite?

• Sum of all sides

• Base times height

• One half of the product of the diagonals

• Length times width

If one diagonal of a kite is 20 units and the other is 10 units, what is the area?
