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.

This lesson covers the properties of a rhombus. Students learn the definitions of a rectangle, a rhombus, and a square. Students also learn the following theorems. The diagonals of a rectangle are congruent. The diagonals of a rhombus are perpendicular and bisect the angles of the rhombus. The midpoint of the hypotenuse of a right triangle is equidistant from the three vertices. Students are then asked to solve problems related to these concepts using Algebra.
