Asked by cassie

When constructing a perpendicular bisector, why must the compass opening be greater than one half the length of the segment
Answered by Damon
Oh come on cassie. Try it!
If the opening does not reach halfway, no way you can swing it off to the side and get the swings from both ends to intersect!
Answered by Damon
Try is with a line segment on your desk and use your fingers for a compass.
