Activities for Students: Classifying Triangles and Quadrilaterals

Orlando B. Alonso and Joseph Malkevitch Edited by Ruth Dover and Patrick Harless 

March 2013, Volume 106, Issue 7, Page 541

Abstract:
The classification of shapes in middle and high school geometry often seems very mysterious to students, featuring strange terms such as isosceles, trapezoids, and kites, which are defined by a mixture of parallelism and metric ideas. The activities introduce a more natural way to classify triangles and quadrilaterals.
