Locus Problem (3)
- Tim Brzezinski
In the applet below, O is the center of the circle shown. Point D is a point that lies ON this circle. Point A is a point that ALWAYS LIES OUTSIDE the circle. (You can move it anywhere you'd like). The pink line is the perpendicular bisector of the segment with endpoints A and D. Drag point D around the circle a few times. What do you see? Describe in detail! Feel free to alter the locations of A and the gray point (radius changer). Then clear the trace and drag point D around again. Why does this occur?
Please go to the Locus Construction (3) Task and begin!
