How do you find a 90-degree triangle?

How to find the sides of a right triangle

  1. if leg a is the missing side, then transform the equation to the form when a is on one side, and take a square root: a = √(c² – b²)
  2. if leg b is unknown, then. b = √(c² – a²)
  3. for hypotenuse c missing, the formula is. c = √(a² + b²)
