Date: 25 Jul 1995 09:25:28 -0400 From: Dr. Ethan Subject: Re: Geometry Hey Ricky, Well, A^2 + B^2 = C^2 is only true if we know what a, b, and c stand for. This formula refers to a, b, and c being the sides of a right triangle. If that is true, then the sum of the squares of the length of the sides of the legs of the triangle is equal to the square of the hypotenuse. That probably didn't make sense so I will try a picture. |\ | \ | \ | \C A| \ | \ | \ |_______\ B In this example, since this a right triangle, A^2 + B^2 = C^2 This important result is called the Pythagorean Theorem. If you would like to see a better drawing of this and you have access to a graphical Web browser, write to me and I will post a picture for you. Hope This Helps. Ethan Doctor On Call
