If you have a right triangle and you know the 2 legs is there another way to find the hypotenuse without using A squared + B Squared = C squared? Is there a way so you do not have to find the square root?

Including the Phthagorean Theorem (in a right triangle, the square of the measure of the hypotenuse equals the sum of the squares of the measures of the two legs), the other methods are:
a) In a 45-45-90 triangle, the measure of the hypotenuse is equal to the measure of a leg multiplied by SQRT(2).
b) In a 30-60-90 triangle, the measure of the hypotenuse is two times that of the leg opposite the 30o angle. The measure of the other leg is SQRT(3) times that of the leg opposite the 30o angle.

Depending on the numbers, you can usually make an educated guess as to the number that the hypoteneuse will be. However, to get the exact answer (particularly if it is not a whole number, but a decimal or irrational), then you must you the pythagoreon theorem.

Not that I have ever seen. That is typically the easiest way, as long as you have a calculator.

pythagoras is the easiest way i noe. i dun tink theres another way though. depends on the question actually.

That's the only way and it's easy, so why not do that?

what's wrong with the pythagorean?
