How many equilateral triangles in the plane have two vertices in the set {(0, 0), (0, 1), (1, 0), (1, 1)}?

So in order to solve this problem, we have to graph out these points:
. .
We can see that these are now a square, and from this square since all of the sides are equal, we can make 4 equilateral triangles.
