# How do you find the polar coordinates of the point (-2,0) ?

The polar coordinates of $\left(x , y\right) = \left(- 2 , 0\right)$ is $\left(r , \theta\right) = \left(2 , \pi\right)$.
Since the distance of the point from the origin is $\sqrt{{\left(- 2\right)}^{2} + {\left(0\right)}^{2}} = 2$,
so $r = 2$.
the positive x-axis makes ${180}^{\circ}$, whcih is $\pi$ radians; therefore, $\theta = \pi$.
