Bisect a Segment and Perpendicular Bisector Construction
As your geometry learners rotate through four stations exploring segment bisectors and perpendicular bisectors, they practice using the tools of geometry. A compass and straight edge, Geometers Sketch Pad, paddy paper, marker, string,...

Similarity and the Angle Bisector Theorem
Identifying and verifying reproducible patterns in mathematics is an essential skill. Mathematicians identify the relationship of sides when an angle is bisected in a triangle. Once the pupils determine the relationship, they prove it to...
