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.
$S_1 =$ , $S_2 = $ $ 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.
$S_1 =$ , $H = $ $ S_2 = $
