This applet shows the Thales intercept theorem

In this applet you can move a lot of things: [br]1. The points that control the grey lines.[br]2. The points that control the blue lines that intercept with them.[br][br]Experiment moving them and try to reach some conclusions about the ratio between segments in the grey lines. The calculations are made for you at the right.[br][br][br]Ricardo García Mesa, matesytic@gmail.com
