Description: The task requires students to classify triangles according to angle and side properties. Students use Geometer's Sketchpad to manipulate triangles to see that constructed triangles have imposed restrictions whereas drawn triangles can be freely dragged to change properties. Students will use mathematical language to describe geometric concepts as they explore, manipulate, and hypothesize about the classifications of triangles.
