To create a circle tangent at three points, set running object snaps (OSNAP)
to Tangent and use the three-point method to create the circle.

A polyline is a connected sequence of line segments created as a single object.
You can create straight line segments, arc segments, or a combination of the
two.
Multisegmented lines provide editing capabilities unavailable for single lines.
For example, you can adjust their width and curvature. After you've created
a polyline, you can edit it with PEDIT or use EXPLODE to convert it to
individual line and arc segments. You can
