Perpendicular Bisector Construction

Understanding a MIDPOINT. The definition is a point that divides a segment into 2 equal segments. Use the midpoint tool to visualize where the midpoint is. Drag A and/or B to see the impact on the midpoint.
Understanding a PERPENDICULAR BISECTOR. The definition is a line that is both perpendicular to and divides a segment into 2 equal segments. Use the perpendicular bisector tool to visualize where the perpendicular bisector is. Drag A and/or B to see the impact on the perpendicular bisector.
Construct the perpendicular bisector using the same steps from your notes in class. When using the compass tool:
  • you must click on two points to set the measurement of your compass.
  • Then click on where you want the compass centered.
  • YOU WILL NEED TO ADD A POINT C FOR THE FIRST STEP OF THIS CONSTRUCTION
Drag A and/or B to see the impact on the perpendicular bisector.
