GraphicMaths Pythagoras Triangle Solver
Pythagoras' Theorem can be used to calculate the third side of a right angled triangle if two sides are known. Enter the lengths of any two sides and leave the third side blank. More...
A right-angled triangle has three sides, a, b and c (where c is the hypotenuse). If you know the lengths of two of the sides, this calculator will find the third side, using Pythagoras' theorem. The theorem is: $$ a^2 + b^2 = c^2 $$ For example, if you know that side a has length 4, and side c (the hypotenuse) has length 5, then enter the values 4 and 5 into boxes a and c. You must leave box b blank. The calculator will find the value of sibe b
