Solution
The given points are A(3, 0), B(3, 3) and C(0, 3). These points can be plotted on the co-ordinate plane as follows:

The x co-ordinate of point is its distance from the Y-axis and y co-ordinate of point is its distance from the X-axis.
Here, OA = AB = BC = OC = 3 units
Therefore, the figure formed is a square.
