Which is the result derived from the pythagorean theorem?

Answer 1

If you know any two sides of a triangle (and know that one of the angles is a right angle), you can calculate the third side.

Also, if you know the third side of a triangle, you can check whether the angle opposite the hypothenuse is a right angle or not.

Answer 2

The Pythagorean Theorem, states, that 'for any right angled triangle the hypotenuse squared is equal to the squares of the other two sides'.

Algebraically expressed as

h^2 = S^2 + s^2

Where 'H' is the hypotenuse, and 'S' and 's' are the other two sides.

The classic example is the 3,4,5 triangle.

5^2 = 4^2 + 3^2

25 = 16 + 9

25 = 25
