Pythagore's most famous theorem is the formula for calculating the hypotenuse of a right angle triangle. This theorem was also modified to create the formula for calculating the distance between two points on a cartesian plane. Pythagore's theorem is the following: $$ a^2 + b^2 = c^2 $$ Where \(c\) is the hypotenuse of the triangle and \(a\) and \(b\) are the lengths of the other two sides of the triangle. We some basic manipulation of this expression (take the square root of both sides), we can see that the length of the hypotenuse is calculated using: $$ c = \sqrt{a^2 + b^2} $$ Use the calculator below to verify or solve pythagorean theorem problems.

The length of the hypotenuse is .
