Perpendicular Bisector: Quick Recap

In the app below, the purple line (p) is said to be the perpendicular bisector of the segment with endpoints SS and SHS. Move points SS snd SHS around. (Don't touch the vertical slider yet.) How would you describe what a perpendicular bisector of a segment is? Please describe below.

After you answer the question above, go on to the questions below this app.

Complete the following in the app above.

  1. Slide up the black slider (on the right).
  2. Drag the red point (SS) on top of Stop & Shop.
  3. Drag the blue point (SHS) on top of Southington High School.
  4. Click the Show More checkbox (in the upper right corner).
  5. Drag that LARGE PURPLE POINT around.
