Use the compass tool to find the perpendicular bisector of the given segment. To do this on Geogebra, do the following:[br][list][*]Create a segment that is longer than half of the length of given segment (you can also just use the original segment itself)[/*][*]Use the compass tool to construct two circles with radius more than half of the length of the original circle, one centered on each of the endpoints. (It is ok to use the original circle as the radius of each circle). Note: It is critical that each circle has the same radius, whatever you decide to make it.[/*][*]The perpendicular bisector will be the line that passes through the points of intersection of the two circles.[/*][/list]
