Notice how the roads intersect at right angles. This means the lines are perpendicular. Visit the interactive worksheet on perpendicular bisectors. Once you have completed the worksheet you will be asked to describe what the distance was from any point on the perpendicular bisector to both endpoints of the line segment in the discussion.

Go to the 3.02 Discussion: Perpendicular Bisector and answer the following questions. Then, read another student's answer and critique it. Did they notice somehting you did not? Can you add additional information to their answer?

  • What do you notice about the point on the perpendicular bisector?
  • Move the point, what do you notice?
  • What type of triangles does the perpendicular bisector create?

At the end of this lesson, student will be able to:

  • Prove points on a perpendicular bisector is equal lengths from the endpoints of the segment
  • Construct perpendicular bisectors and lines.

The above objectives correspond with the Alabama Course of Study: Geometry Standards: 1
