Peer reviewedLitchfield, Daniel C.; Goldenheim, David A. – Mathematics Teacher, 1997
Describes the solution to a geometric problem by two ninth-grade mathematicians using The Geometer's Sketchpad computer software program. The problem was to divide any line segment into a regular partition of any number of parts, a variation on a problem by Euclid. The solution yielded two constructions, one a GLaD construction and the other using…
