    if you dilate the rectangle, point A' will lie somewhere on that ray. If you dilate to expand it out, then A' will lie to the left of A |dw:1439337762267:dw|

    In a sense, this rectangle is bigger because it is closer to the screen. Think of it as a 3D perspective.

    when we dilate every point, we just move the points outward from the center they will still lie on the same line |dw:1439338225977:dw|
