# 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. The screen gets busy (and dark)--the viewer may want to open to 'full screen' to see everything. The sound is a little low
