Answer:
It is the longest side of a right triangle.
Step-by-step explanation:
A right triangle has two legs, then the (i call it a slope) hypotenuse connects the two from the top of one of leg to the end of the bottom leg.
you can calculate the hypotenuse via the Pythagorean theorem. which is A^2+B^2=C^2
Or: Leg 1^2+ Leg 2^2= Hypotenuse^2
