📐 Hypotenuse Calculator

A hypotenuse is the longest side of a right triangle. It's the side opposite to the right angle (90°). The hypotenuse is always longer than either of the other two sides (legs) of the triangle.

To calculate the hypotenuse using the Pythagorean theorem, use the formula c = √(a² + b²), where 'c' is the hypotenuse and 'a' and 'b' are the two legs of the right triangle. Simply square both legs, add them together, and take the square root of the result.

Yes, you can find the hypotenuse using one side and an angle. If you know a leg and its adjacent angle, use c = a / cos(angle). If you know a leg and its opposite angle, use c = a / sin(angle).

In a right triangle, for any given angle (not the right angle), the adjacent side is the side that forms the angle along with the hypotenuse, while the opposite side is the side that doesn't touch the angle vertex.

In a 45-45-90 triangle (isosceles right triangle), if each leg has length 'a', then the hypotenuse has length a√2. This is approximately 1.414 times the length of either leg.

In a 30-60-90 triangle, if the shortest side (opposite the 30° angle) has length 'a', then the hypotenuse has length 2a, and the longer leg (opposite the 60° angle) has length a√3.

No, this calculator is specifically designed for right triangles (triangles with a 90° angle). For other triangles, you would need different formulas like the Law of Cosines or Law of Sines.
