How do you find the missing side of a 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)
