Solve a right triangle using two independent measurements. Find missing sides and angles with formulas, worked examples, and step-by-step guidance.
I built Right Triangle Solver because most triangle calculators give you an answer and stop there. Students need to see the working, so each of the 52 calculators shows every step, from the classic 3-4-5 example to the ladder check. It is free, no sign-up, and it works in 19 languages. I would love to hear which calculator you use most, and what is missing.
