6th graders have been exploring properties of
triangles using the Geometer’s Sketchpad
software. The students constructed an
equilateral triangle, measured all angles and
sides, and explained what connections exist
between them.  Further exploration enabled
them to discover the relationship that exists
between the sides and angles in other types
of triangles.  In addition, students were able
to classify triangles according to the lengths
of their sides and the measure of their angles.
