Pythagorean Theorem Calculator

An online calculator to solve for the hypotenuse and side of a right triangle using the pythagorean theorem is presented. Let $S_1$ and $S_2$ be the sides of a right triangle and $H$ its hypotenuse. Pythagora's theorem states the relationship between the sides and hypotenuse as following:

$H^2 = S_1^2 + S_2^2$
Which may be solved to find:
1) the hypotenues: $H = \sqrt{S_1^2 + S_2^2}$ , given the sides $S_1$ and $S_2$,
2) side $S_1$: $S_1 = \sqrt{H^2 - S_2^2}$ , given $H$ and $S_2$
3) and Side $S_2$: $S_2 = \sqrt{H^2 - S_1^2}$ , given $H$ and $S_1$.

Use the Pythagorean Theorem Calculator to Calculate the Hypotenuse $H$ Given the Two Sides $S_1$ and $S_2$.

 Enter side 1 and side 2 of the right triangle, as positive real numbers and press "enter". The output is the hypotenuse of the triangle. $S_1 =$ 4.5 , $S_2 =$3.8 $H =$

Use the Pythagorean Theorem Calculator to Calculate One Side $S_2$ Given the Other Side $S_1$ and the Hypotenuse $H$

 Enter side 1 and the hypotenuse of the right triangle, as positive real numbers and press "enter". The output is the second side of the triangle. $S_1 =$ 3.9 , $H =$7.9 $S_2 =$
