Here you will learn how to construct a perpendicular bisector of line segment AB. Using only the compass and straightedge.
If you need help you can select the boxes to show you the next step. make sure to use the measuring tool to ensure you not only have created a bisector but a perpendicular one as well.

**Written Steps**:**Step 1)**Construct 2 circles centered at point A and B with radius AB**Step 2)**Find the intersections of the two circles and label them DC**Step 3)**Construct segment DC**Step 4)**find the intersection of segment DC and segment AB make sure to ensure by measure distance and angle that you truly created a perpendicular bisector.
