segment are equidistant from the ends of the segment. Activity 3: One student stands on point A while another student stands on point B. The eight pairs of ribbons are divided equally between these two students, with each student holding one end of every pair. Other students pick up the free ends of the ribbons and move until each ribbon is pulled taut. All of these students should end up standing on the perpendicular bisector. This activity leads to development of the idea that points that are equidistant from the endpoints of a segment lie on its perpendicular bisector. Guiding Questions: What are the properties of a perpendicular bisector of a line segment?
