MPM2D1-02 Circumcentre and Centroid 2016-10-06


We used cardboard triangles today. We drew the three medians on one side and the three perpendicular bisectors to the sides on the other. 

We noticed that the perpendicular bisectors all met in a single point, and that a circle centred on that point could be drawn so that each vertex of the triangle would be on the circumference. This point is called the circumcentre.

We also noticed that the medians connected in a single point, which was the gravitational centre for the triangle. This point is called the centroid. 

No homework tonight, and you won’t need your textbooks tomorrow as we’ll be focusing on literacy work.
