Overview
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.
