I think it can be answered best by showing the construction in images. Here is how to construct an angle bisector: And here is a method for constructing the perpendicular bisector of a segment: The construction shown above also gives you the midpoint of a segment. To construct the A-median of ABC, connect the midpoint of BC and vertex A. I hope this helps! Best regards, - Doctor Floor, The Math Forum http://mathforum.org/dr.math/
