To rotate a shape around the Y axis to form a cylinder, you would need two points on the same X axis,
When the shape is rotated it needs to be a cylinder, so the shape you need has to be either a square or a rectangle.
you can pick any X and Y coordinates that would make a square or rectangle as long as one other X is the same as Point A.
You can use Point B (0, 0), Point C (1,0) and Point D (1,3)
