Exploring the configuration of the points that keep an angle constant
1. Move the point P and notice that the angle that is formed by APB remains constant at 30 degrees.
2. When you move P where does it appear that all of the points that P could be appear to lie?
3. Once you've made a guess about the configuration of all of the points, P, click the box and trace the path as you move the point P. Was your guess right?
4. Why does the configuration look the way it does? Justify your answer.
