Can a triangle be made using the side lengths of 1, 17, 3?
a
Yes.
b
No, the sum of the shortest sides measures less than the longest side.
c
No, the sum of the shortest sides measures more than the longest side.
So if you have a triangle and you have the side 1,17,and 3 one of the sides with be longer than the whole triangle. That's the reason why triangle sides have to be equal or at least close to equal
