Check out the OpenLayers.Geometry.Polygon.createRegularPolygon func:

You can use the select feature control to allow your users to select
features. Then, you can add a button which on click will destroy the
selected feature(s). Your button may be be based on
OpenLayers.Control.Button.

Hope this helps,
