I would argue that mathematically, there are 540 triangles with no collinearity even if due to the scale of the triangle, they look like a straight line.

But I've put that solution with the 516 triangle solution.

Doesn't match the solution exactly but theoretically these are all triangles which have a non (rounded to zero) area....
