Median of Triangle:  What is it?



Note:  There are several "breaks" in the video.  But no break-dancing.




Construction : Median of a Triangle




Woksheet :Median and Centroid constructions




Proof:  Triangle Medians all meet at a common point (centroid)




Homework:  watch informal proof  (Triangle Medians and Centroid), copy down diagrams and work, turn in for quiz grade tomorrow.
