Illuminations: Rectangles and Parallelograms

Students use dynamic software to examine the properties of rectangles and parallelograms, and identify what distinguishes a rectangle from a more general parallelogram.

Using spatial relationships, they will examine the properties of two-and three-dimensional shapes. This Internet Mathematics Excursion is based on an E-example from the NCTM Principles and Standards for School Mathematics.
