The sum of the inner angles of any triangle is always 180°, i.e. you have
In the particular case of an equilater triangle, all three angles are the same, so
and the expression becomes
which implies
So, if you rotate the triangle with respect to its center by 60 degrees, the triangle will map into itself. In particular, if you want point A to be mapped into point B, you have to perform a counter clockwise rotation of 60 degrees with respect to the center of the triangle.
Of course, this is equivalent to a clockwise rotation of 120 degrees.
Finally, both solutions admit periodicity: a rotation of 60+k360 degrees has the same effect of a rotation of 60 degrees, and the same goes for the 120 one (actually, this is obvisly true for any rotation!)

We would know if a system is consistent, inconsistent, or coincident depending on the number of solutions it has. If it has only one solution, the system is said to be consistent. If it has none, the system is inconsistent; and if the system has an infinite number of solutions, it is said to be consistent and coincident.
Let's solve the system to know how many solutions it has.
Notice that dividing the second equation by 2 would yield the exact same equation as 1. This would therefore allow us to conclude that AN INFINITE NUMBER of pairs of (x,y) coordinates would satisfy the system. Thus, the system is said to be
consistent and coincident.
