The Pythagorean Theorem (aka. The length of the side is is found using the formula: In the formula, a and b are the lengths of the shorter sides and c is the length of the hypotenuse. There are a few methods of obtaining right triangle side lengths. Put another way, if you know the lengths of a and b, you can find c. In the triangle above, you are given measures for legs a and b: 5 and 12, respectively. It says that the sum of the squares of the lengths of the legs is equal to the square of the length of the hypotenuse. Let AB = a = 20, BC = b = 21. 6.1b - Using the Pythagorean Theorem The Pythagorean Theorem can be used to find a missing side of any right triangle, to prove that three given lengths can form a right triangle, to find Pythagorean Triples, and to find the area of an isosceles triangle. Take the square root of each side. (Use commas to separate your answers.) Given a right triangle has legs labeled 3m and 2m+10. The Pythagorean theorem is a simple theorem that states that - for a right angled triangle the square of the length of the hypotenuse is equal to the sum of the squares of the length of the remaining two sides.
