Pi is a ratio that allows us to make calculations on a circle, but do polygons have their own versions of pi? In this circle, we will use the circle as a basis for thinking about how to calculate ratios in other shapes. Pi, as we know it, is useful for a radius or diameter, but what happens when we start connecting random points on a circle? This will lead us to the basis for trigonometry!

Note - Circle Prerequisites:

(1) Can use the Pythagorean Theorem

(2) Has not explored the concept of pi beyond circles
