One point is Origin.

The point on X-axis is given by:
  the line makes an angle of 0 degrees with X-axis so,(0+2aCos0 ,0+2a sin0)  ⇒ (2a,0)

The point above X-axis is given by:
  this line makes 60 degrees with X-axis. So, point will be
(0+ 2aCos60, 0+2aSin60) ⇒ (a, √3 * a).

So, the points are (0,0) (2a,0), (a,√3 * a).

Is it understandable?
