The gfc of any two even numbers is always even

True because then all of the factors will have to be even as well. I am in Geometry (high school math)

If you are asking if the question is true or false 
it is true because . Two even numbers are each divisible by 2. The GCF must therefore always have two as one of its factors; this makes it even.

i'm not sure on this one, most likely correct.

good luck!
