Circle

Usage

• Circle[{x, y}, r] is a two-dimensional graphics primitive that represents a circle of radius r centered at the point x, y.
• Circle[{x, y}, {, }] gives an ellipse with semi-axes and .
• Circle[{x, y}, r, {, }] represents a circular arc.

Notes

• Angles are measured in radians counterclockwise from the positive direction.

• Circle[{x, y}, {, }, {, }] yields a segment of an ellipse obtained by transforming a circular arc with the specified starting and ending angles.

• Scaled[{, }] or Scaled[{, }, {, }] can be used in the radius specification. The are in scaled coordinates, and the are in ordinary coordinates.

• Offset[{, }] can be used to specify radii in printer's points.
