Medians of a Triangle

Mathematics — Second Preparatory

Common mistakes

Confusing a median with an altitude. A median joins a vertex to the midpoint of the opposite side, while an altitude meets the opposite side at a right angle.
Dividing the distance from the vertex to the centroid by 3 instead of multiplying the median by two thirds.
Finding the centroid by dividing the sum of the coordinates by 2 instead of 3.
Believing that the three medians do not meet at one point. In fact, they always meet at the centroid.
