how do you get the other sides of a right triangle given the hypotenuse? is it by Pythagorean theorem?

Question

anonymous · Answer

to find the hypotenuse it is a^2 +b^2= c (c is the hypotenuse) so i would imagine you would do the inverse of that

anonymous · Answer

for a right triangle if you are given an angle (other than the 90) you can use trig.  With x=the angle measure sin(x)=(opposite side)/(hypotenuse)  and cos(x)=(adjacent side)/(hypotenuse)  solve for the side you are looking for and you should get your answer.

^She's right. There are infinite possibilities for the other two sides for a given hypotenuse. But if the other two sides are given, only one hypotenuse can exist.

The Pythagorean theorem tells you this:
$$C² = A² + B²$$Let C be the hypontenuse then and let's say you want to get the side A then:
$$A² = C² - B²$$Thus:
$$A = \sqrt{C² - B²}$$That's when you are given C and B. Otherwise, with angles, use what TMane said.
