# CirclePoints

CirclePoints[n]
gives the positions of n points equally spaced around the unit circle.

CirclePoints[r,n]
gives the positions of n points equally spaced around a circle of radius r.

CirclePoints[{r,θ1},n]
starts at angle θ1 with respect to the axis.

CirclePoints[{x,y},rspec,n]
centers the circle at {x,y}.

## DetailsDetails

• For positive integer n, CirclePoints[n] generates a list of vertices for a regular n-sided polygon, oriented so its base is horizontal.
• In CirclePoints[n], n does not have to be an exact integer. The angles between successive vectors are always .
• Unless explicitly given as a Quantity object, the angle θ1 is assumed to be in radians, counterclockwise starting from the axis. (Multiply by Degree to convert from degrees.)
• If the angle θ1 is not given, it is assumed to be π/n-π/2, so that for integer n the vectors correspond to a regular polygon with its base horizontal.
• All arguments of CirclePoints except n can be symbolic. They can also be Quantity objects.
