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

This lesson covers the area of a trapezoid. Students learn that a trapezoid is a quadrilateral with one pair of parallel sides, and the formula for the area of a trapezoid is 1/2 times (base 1 + base 2) times height. For example, the area of a trapezoid that has bases of 10 centimeters and 12 centimeters and a height of 8 centimeters is 1/2 times (10 + 12) times 8, which simplifies to 1/2 times 22 times 8, or 11 times 8, which is 88 square centimeters.

This lesson covers wind and current problems. Students learn to solve wind and current word problems using a system of linear equations, as demonstrated in the following problem. Into a headwind, the plane flew 2000 miles in 5 hours. With a tailwind, the return trip took 4 hours. Find the speed of the plane in still air and the speed of the wind. The two variables used in this problem are p, the speed of the plane in still air, and w, the speed of the wind. So the speed of the plane with a tailwind can be represented as p + w, and the speed of the plane against a headwind can be represented as p -- w. Note that this problem requires a chart to organize the information. The chart is based on the formula rate times time = distance. The chart is then used to set up the two equations.
