This is a calculator for the Phytagorean Theorem. Given the two legs of
a right triangle (legs a
and b),
you can calculate the hypotenuse (c);
or, if you're given the hypotenuse (c)
and a leg (either a
or b), you
can find the other leg of the right triangle.

A
corollary of the theorem is that in any right triangle, the hypotenuse
is greater than any one of the legs, but less than the sum of them.

Examples
- Pythagoras' Triangle

Example 1:

If one leg of a right triangle is 3 inches and the other leg
is 4, what's the length of the hypotenuse?

You can enter into the calculator Leg a = 3 Leg b = 4

and you get

Hypotenuse c
= 5

Example 2:

If the hypotenuse of a triangle is 10 ft and a leg is 6 ft, how long is
the other leg of the triangle?

You can enter Hypotenuse c
= 10 Leg a = 6

and you get

Leg b = 8
