Find the missing side of a right triangle using the Pythagorean theorem with step-by-step solutions
Right triangle with legs a, b and hypotenuse c
The Pythagorean theorem states that in a right triangle, the square of the hypotenuse (the longest side) equals the sum of squares of the other two sides. It's written as a² + b² = c², where c is the hypotenuse and a and b are the legs.
