Can you construct inscribed figures?

Let's review the steps for inscribing a regular polygon in a circle:

Steps Using a Protractor Using a Compass
1 Calculate the angle between adjacent vertices.

\(\mathsf{ \alpha = \frac{360°}{n}}\)
Calculate the length of each side of the regular polygon.

\(\mathsf{ \text{l} = 2r \text{ sin}(\frac{360°}{n})}\)
2 Marks the points on the circle for each successive angle. Marks the points on the circle for each successive side length.
3 Join the points on the circle with line segments. Join the points on the circle with line segments.
