## Reflection: Exploring Our Concepts with Dynamic Geometry Software - Section 1: Going Over the Coordinate Geometry Practice Problems

Problem_5 turned out to be a great segue into parallel lines.  My students realized that not only were the opposite sides of the quadrilateral congruent, but they also looked parallel, and wanted to know how they could prove that.  This resulted in a good discussion, and helped to lead into our explorations on the dynamic software.
