The Pythagorean Theorem states: In any right triangle, the area of the square whose side is the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares whose sides are the two legs (the two sides that meet at a right angle).

This calculator calculates for the length of one side of a right triangle given the length of the other two sides. Example 1: Compare the lengths of the sides of the following triangle. (From here solve for X). Example: Identify the hypotenuse, adjacent side and opposite side in the following triangle: a) for angle x b) for angle y. Then use Heron's formula and trigonometric functions to calculate area and other properties of a given triangle. Perimeter = a + b + h . Solve triangle by entering one side and two angles (adjacent and opposite). It’s defined as: 1.
