Pythagorean TheoremDate: 5/14/96 at 19:48:32 From: Anonymous Subject: Pythagorean theorem What is the Pythagorean theorem? Date: 5/16/96 at 21:2:40 From: Doctor Ken Subject: Re: Pythagorean theorem Hello! Here's what the Pythagorean Theorem says: let's say you have a right triangle ABC, and the right angle is at C. Then the sides of the triangle have certain lengths. Let's give them some names: call one leg of the triangle "a," the other leg "b," and the hypotenuse "c," like in this picture: A |\ | \ | \ Then Pythagoras says that | \ a squared plus b squared equals c squared. | \ Another way to write that is a^2 + b^2 = c^2. | \ |b \c | \ | \ | \ | \ | \ |____________\ C a B For instance, if the lengths of your triangle's sides are 3, 4, and 5, then see how it works: 3^2 + 4^2 = 5^2 9 + 16 = 25. It's true! -Doctor Ken, The Math Forum Check out our web site! http://mathforum.org/dr.math/ |
