  1. so, move left-right 1 and up-down 2

    or left-right 2 and up-down 1.

    One such point will be (1+1,2+2) = (2,4)

    I think you will find 8 such points, not 4.

  2. Step1: Mark the point (1,2) on a Cartesian plane.
    Step2: Go 2 units up and 1 unit right that will be your point A (2,4)
    Step3: Go 2 units up and 1 unit left that will be your point B (0,4)
    Step4: Go 2 units down and 1 unit right that will be your point C (2,0)
    Step5: Go 2 units down and 1 unit left that will be your point D (0,0)

  3. These are your four points
    A: (2,4)
    B: (0,4)
    C: (2,0)
    D: (0,0)
    Hope this helps
