Answer:
In order to find out what the hypotenuse of a right triangle is, you need to use the Pythagorean Theorem:
a^2 + b^2 = c^2
In this equation the a and b stand for the length of the legs of the triangle. The c stands for the hypotenuse. Here's an example on how to solve it:
Say you have a right triangle. The two sides are 3 inches and 4 inches. You need to figure out the hypotenuse, so here's what you have to do:
1) Plug in your numbers to the equation.
(3)^2 + (4)^2 = c^2
2) Square the 3 and the 4
9 + 16 = c^2
3) Add the 9 and the 16
25 = c^2
4) Square root both sides to get c by itself
5 = c
Now that you have c, you have the hypotenuse!
