# What does a polar coordinate system look like?

A polar coordinate system consists of a polar axis, or a "pole", and an angle, typically $\theta$. In a polar coordinate system, you go a certain distance $r$ horizontally from the origin on the polar axis, and then shift that $r$ an angle $\theta$ counterclockwise from that axis.
This is a more detailed picture, depicting a whole polar coordinate plane (with the $\theta$'s in radians):
The origin is in the middle, and each circle represents a different $r$ (which is actually a radius). If you follow the line of that given circle with radius $r$ along the angle, you can get polar coordinate points in the form $\left(r , \theta\right)$
