A Hypotenuse is the line segment opposite to the right-angle.The Hypotenuse is also the longest side of a Right Triangle. Pythagoras is credited with discovering the relationship between the sides of a right triangle, but the truth is highly debated. Dan uses golf to explore right-angled triangles, introducing the hypotenuse by solving a dog-leg hole in one. The theorem appears more complicated than it really is, and there is no easy reference to begin the memorisation process. Overall rating: 4.33: 4.33. Convince me that the area of this square is 10cm 2. There are many ways to prove Pythagoras’ Theorem. If a triangle has a right angle (also called a 90 degree angle) then the following formula holds true: a 2 + b 2 = c 2. Creative Commons "Sharealike" Other resources by this author . Video Tutorial .
