Area Of Triangles: The formula to calculate the area of a triangle

The video tutorial explains how to calculate the area of a triangle by first reviewing the area of a rectangle. It demonstrates that by drawing a diagonal in a rectangle, two triangles are formed, and thus the area of one triangle is half the area of the rectangle. The formula for the area of a triangle is derived as 1/2 times the base times the height. This formula is applicable to all triangles, and the video emphasizes the importance of identifying the correct base and height.

Why is the area of a triangle defined as 1/2 times the base times the height?

Explain the difference between the height of a triangle and the legs of the triangle.
