Constructing The Perpendicular Bisector
Use the same method you used in Constructing an Equilateral Triangle to construct the points of intersection of the two circles centered at the green and red points. Now, draw the line passing through these points of intersection. To do so, select "Line" from the Choice Menu and follow the instructions. You have just drawn a line that bisects the line segment whose endpoints are the green and red dots. In other words, you have drawn a line that is perpendicular to the given line segment and intersects it at a point half way between it's two endpoints.
