Area of diagonal generated triangles of rectangle are equal | Geometry | Khan Academy
By Khan Academy
In this video, Mr. Khan draws a box and two intersecting lines that produce several triangles. Mr. Khan proves that the area of these diagonal-generated triangles of the rectangle are equal. He goes over the formula for finding the area of a triangle. Sal Khan is the recipient of the 2009 Microsoft Tech Award in Education.
