Constructing Angle Bisectors

 

Students learn how to construct angle bisectors using a pair of compasses and a straight edge.

Later, students use equilateral triangles to construct 30° and 45° angles as learning progresses.

Differentiated Learning Objectives
  • All students should be able to construct an acute angle bisector.
  • Most students should be able to bisect an acute, obtuse, right angle and straight line.
  • Some students should be able to find the equidistant point in a polygon using angle bisectors.
