Find the area of a right triangle - Online Tutor - Free Math Videos

The video tutorial explains how to find the area of a triangle by comparing it to a rectangle. It highlights that the area of a triangle is half the area of a rectangle formed by its base and height. The tutorial provides a step-by-step example using specific measurements and emphasizes the importance of using base times height for right triangles. The video concludes with a recap of the method, reinforcing the concept that the area of a right triangle is half the product of its base and height.

What is the relationship between the area of a triangle and a rectangle?

• A triangle's area is twice that of a rectangle.

• A triangle's area is half that of a rectangle.

Which formula is more appropriate for calculating the area of a triangle?

• Length times width

• Length times height

• Base times height

• Perimeter times height

In the context of right triangles, which formula can be used to find the area?

• Base times length

• Base times perimeter
