Understanding the Area of a Triangle in a Coordinate Plane

This video tutorial explains how to find the area of a triangle on a coordinate plane. It begins with a review of the area formula for triangles, highlighting its relation to rectangles. The tutorial then guides viewers through calculating the base and height using the x-axis, followed by applying the area formula. Finally, it provides a visual demonstration to reinforce the concept that a triangle's area is half that of a rectangle.

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

• A triangle is one-third the area of a rectangle.

• A triangle is the same area as a rectangle.

• A triangle is half the area of a rectangle.

• A triangle is twice the area of a rectangle.
