How to Construct the center of gravity in a triangle and two other special points in a triangle.

This video will use a compass and straight edge to construct special concurrent lines in a triangle and show you the significance of the point of concurrency (intersection). The angle bisectors of the triangle intersect to form the incenter of the triangle. The perpendicular bisectors intersect to form the circumcenter of the triangle. The medians of the triangle (the line from the vertex to the midpoint of the opposite side) intersect to form the centroid, which is also known as the center of gravity. Watch this video to see the significance of the points of concurrency. Better yet, pick up your compass and straight edge and create the constructions with the video.
