triangle has 3 sides ABC with C being the hypotenuse and A,B being the 2 other smaller sides.Ussing the formula below u can find the hypotenuse of any triangle and can also be used to find one of the sides.
A%5E2%2BB%5E2=C%5E2
sqrt%28A%5E2%2BB%5E2%29=C
for example: A triangle has one side 3 feet long and another side 4 feet long, how long is the hypotenuse?
A=3 B=4
A%5E2%2BB%5E2=C%5E2
3%5E2%2B4%5E2=C%5E2
9%2B16=C%5E2
25=C%5E2
sqrt%2825%29=sqrt%28C%5E2%29
5=C hypotenuse is 5 feet long
