Use Pythagoras's equationa^2 + b^2 = c^2

where c is the hypotenuse - the longest side which is opposite the right angle

a and b are the two smaller legs.


So, if the two legs are known and the hypotenuse is unknown:

  1. square the two known sides;
  2. add the numbers together
  3. take the square root.
This is the measure of the hypotenuse.


Suppose the hypotenuse and one side is known, the other is unkown:

  1. square the two known sides;
  2. subtract the smaller answer from the larger;
  3. take the square root.
This is the measure of the missing leg.
