WebMar 31, 2024 · The Pythagorean Theorem can be used to find the length of one side of a right triangle (a triangle with a 90-degree angle): if you have the lengths of the perpendicular sides a and b, for example, you plug the values into the formula a^2+b^2=c^2. Solve for c and you can find the length of the remaining side (the hypotenuse).
