Enter any two values — two sides, a side and an angle — and it instantly computes everything else: the missing sides, both angles, and the hypotenuse. It's built for people who measure in the real world, so you can type the way you actually work: feet and inches, fractions, or metric. Whether you're framing a wall, cutting a rafter, laying out stairs, building a deck, or checking homework, the answer is one tap away.
