5.3 Part 2

Click and drag Point D around so that the D is equidistant to AB, BC, and AC (hint: 2 line segments are equidistant if they have the same length). At any point, you can reset the picture by clicking on the circular loop button in the top right of the picture. If you finish before Mr. Nordman, move A, B, and C around and start over. Challenge: Move A, B, and C around so that the person next to you will have trouble finding the right place to move D.
