Work Step by Step

To plot the point $(r, \theta )=(2, 45^{\circ })$, begin with the $45^{\circ }$ angle. Because $45^{\circ }$ is a positive angle, draw $\theta = 45^{\circ }$ counterclockwise from the polar axis. Now consider $r=2$. Because $r \gt 0$, plot the point by going out two units on the terminal side of $\theta$ .
