Pythagoras Theorem Calculation

In a right angled triangle: the square of the hypotenuse is equal to the sum of the squares of the other two sides. Suppose right triangle with sides a and b and hypotenuse c then c2 = a2 + b2
Or c = √(a2 + b2)
Or a = √(c2 - b2)
Or b = √(c2 + a2)
Select side
Adjacent side (a) =
Opposite side (b) =
Hypotenuse side (c) =
