# Geometry in Motion

Employing Java Sketchpad, this interactive site explores dozens of topics in geometry, allowing the user to drag points and lines of geometric figures, to change curves and angles, and to put "geometry in motion." This visualization helps users make conjectures that can later be verified or rejected through formal proof.
