Pythagorean theorem 3 | Right triangles and trigonometry | Geometry | Khan Academy


By Khan Academy

This three-minute video is from Sal Khan about using the Pythagorean Theorem to solve a word problem: A carpet measures 7 feet long and has a diagonal measurement of square root of 74 feet. Find the width of the carpet Mr. Khan uses computer software for demonstration. The screen is a little 'busy' so the viewer may want to open the screen to 'full screen' to see all more clearly.

Area of inscribed equilateral triangle (some basic trig used) | Circles | Geometry | Khan Academy


By Khan Academy

This video will give you a good feel for what inscribed figures are like. It uses some trigonometry to figure out what the area of an equilateral triangle inscribed in a circle is, given the circle's radius. NOTE: We don't actually need trigonometry to solve this problem. Notice that we can view the equilateral triangle as six identical 30-60-90 triangles, the hypotenuses of which are radii of the circle, then use the 30-60-90 triangle side length ratios to figure out the rest of what we need to know to solve the problem.
