Construct a perpendicular bisector of Segment
Follow the video demonstration from https://www.youtube.com/watch?v=iueUFTq7Xrs
1. Use the compass tool to draw a circle. Set the circle distance greater than half the length of the segment. Place this at one endpoint of the segment.
2. Use the compass tool to draw another circle with the same radius as the first. Set this at the other endpoint.
3. Use the intersection tool. Click each circle. Then both intersections of the circles will be marked.
4. Connect a line through those intersection points.
