Solve a right triangle from its two legs, the everyday shop math behind layout, angle blocks, and checking a part against a print dimensioned with offsets.
Hypotenuse = sqrt(A^2 + B^2). Angle opposite leg A = atan(A / B), measured from leg B.
How it works
Almost every layout problem that involves an offset, a diagonal, or an angled feature reduces to a right triangle. Knowing any two sides gives the third side and both remaining angles through the Pythagorean theorem and basic trig.
FAQ
What if I only have one side and an angle instead of two sides? This calculator is set up for the two-legs case. With a side and an angle, the same trig relationships still apply, just solve for the missing side with sine or cosine first.
