Solve a right triangle with a² + b² = c² (c = hypotenuse).
① ANSWER
④ Visualization
② Steps
③ Why this works
In every right triangle, the square of the hypotenuse equals the sum of the squares of the legs. The hypotenuse is the side opposite the right angle — and it must always be the longest side. If you know two sides, the equation a² + b² = c² lets you solve for the third.
