This example illustrates how students can understand connections between algebra and geometry using dynamic and interactive geometric figures. They can develop an understanding of how to justify geometric relationships in a technological environment.
E-Math Investigations are selected e-examples from the electronic version of the Principles and Standards of School Mathematics (PSSM). The e-examples are part of the electronic version of the PSSM document. Given their interactive nature and focused discussion tied to the PSSM document, the e-examples are natural companions to the i-Math investigations.
