Description

This collection has three lessons related to find special centers in triangles.
Specials centers addressed are the circumcenter and the centroid. The lessons contain geometry standards covered, teacher notes with answers, and the student activities. Each activity requires either software like Geometer’s Sketchpad or Geogebra. As an alternative, the problems may also be solved using traditional Euclidean tools, compass and straightedge.

The titles for the lessons are:
