# Polar Coordinates

Polar coordinates are a way to describe where a point is on a plane. Instead of using x and y, you use the angle theta and radius r, to describe the angle and distance of the point from the origin.

# Polar Coordinates Warmup

The point $$P$$ has Cartesian coordinates $$(3, 4)$$ and polar coordinates $$(r, \theta).$$ What is the value of $$r$$?

The point $$P$$ has Cartesian coordinates $$(0, 1)$$ and polar coordinates $$(r, \theta).$$ What is the value of $$\theta$$ (in radians)?

What are the polar coordinates of the point whose Cartesian coordinates are $$(0, 1)?$$

The point $$P$$ has polar coordinates $$(1, 0).$$ The answer choices are the polar coordinates of various points - which one is also at $$P?$$

What are the polar coordinates of the point having Cartesian coordinates $$(5, 0)?$$
