Geometry: Transformational Puppet

by Texas Instruments


Students construct a puppet using line segments and circles and transformations and then manipulate their puppet to see the effect of changes.

Key Steps

  • Image

    Students use Cabri™ Jr. to construct a puppet. They use the Circle, Segment, and Point On tools to create the head, body, and shoulder, respectively.

    Students must draw a segment for the translation vector.

  • Image

    They use the Translation tool to create the left hand and then use the Reflection tool to create the right hand.

    Each point will need to be joined with a segment to the shoulder point.

  • Image

    Students construct another segment to be used as the translation vector for the legs will be drawn with the first one.

    They drag the point joining the two translation vectors and observe the changes of the arms and legs.
