Why do triangles have to have 180 degrees?

Triangles have to have 180 degrees because every polygon must have the degrees by this formula:

(N-2)*180 = degrees, where N stands for the number of sides. If we subtract 3 from 2, we get 1, and multiplied by 180 gives us 180 degrees. This is true for every polygon.
