Perpendicular Bisector Construction
Instructions
Step 1: Use the CIRCLE TOOL 
to construct a circle with center A and a radius that is more than half the length of segment AB.
Step 2: Use the COMPASS TOOL 
to duplicate circle A and place this circle at center B.
Step 3: Use the INTERSECTION TOOL 
to create points at both intersection points of the circles.
Step 4: Use the LINE TOOL 
to construct a line through both intersection points.
Step 5: Use the INTERSECTION TOOL to create a point at the intersection of segment AB and the line you constructed in Step 4.
The line you created in Step 4 is the perpendicular bisector of segment AB.
The point you marked in Step 5 is the midpoint of segment AB.
After you complete the example, work on the practice. These will not let you know if you've done them correctly. I will be checking on my computer.
