WebThe common side-based special right triangles are: 3-4-5 Triangle. 5-12-13 Triangle. The triangle name describes the ratio of side lengths. For example, a 3-4-5 triangle could have side lengths of 6-8-10 since they have a 3-4-5 ratio. The image below shows all side length and angle relationships for the 3-4-5 and 5-12-13 triangles. WebCalculate the right triangle’s side lengths, whose one angle is 45°, and the hypotenuse is 3√2 inches. Solution Given that one angle of the right triangle is 45 degrees, this must be a 45°-45°-90° right triangle. Therefore, we use the n: n: n√2 ratios. Hypotenuse = 3√2 inches = n√2; Divide both sides of the equation by √2 n√2/√2 = 3√2/√2 n = 3
