DESCRIPTION
KSEG allows you to interactively create a geometrical construction,
similar to what you can do with a straightedge and compass.
Points may be inserted on the page with right mouse-button clicks,
and then used to form segments, lines, circles, or other geometrical
objects. At any time you can drag existing points around, and watch
how the constructed objects respond.
