Let's first draw by plotting vertices and
To rotate the figure counterclockwise about the origin, we can focus on its vertices.
We will begin by rotating vertex To do so, we will first draw a segment from to the origin. Then, we will draw another segment from the origin to the image of such that both segments are congruent and perpendicular.
Similarly, we will rotate the other vertices to have
By connecting the rotated points, we can finally have the image of
