Pythagorean Theorem Practice With Isosceles Triangles Youtube This video continues with the idea of using the pythagorean theorem in isosceles triangles by looking at two more example problems from the khan academy exer. Substitute the values for a, b and c into the pythagorean theorem, (a)^2 (b)^2 = (c)^2. for one of the two triangles constructed in this example, a = 3, b = 4 and c is what we are solving. therefore, (3)^2 (4)^2 = (c)^2 = 9 16 = 25. the square root of 25 is 5, so c = 5. the isosceles triangle we started with has two sides measuring 5. Practice using the pythagorean theorem to find the side lengths of isosceles triangles. learn with interactive exercises and hints. Contributed. the pythagorean theorem states that if a triangle has one right angle, then the square of the longest side, called the hypotenuse, is equal to the sum of the squares of the lengths of the two shorter sides, called the legs. so if a a and b b are the lengths of the legs, and c c is the length of the hypotenuse, then a^2 b^2=c^2 a2.
