Cabri Jr. In this geometry lesson, 10th graders investigate the
menus, tools, and capabilities of Cabri Jr. as a tool to enhance
student understanding. The lesson includes the construction of a
triangle and the perpendicular bisectors of a triangle and an
investigation into the sum of the measures of the angles of a
triangle. There are four activities in this extensive lesson
plan covering the identity matrix and scaling, the linear
representation of translations, the linear representation of
rotations, and reflections. In small groups, they use the Cabri
II computer program to move objects and make observations. In
their groups, they discuss, solve and answer worksheet questions
for each activity.
