Median of a Triangle

median of a triangle is a line segment (shown in red) joining any vertex (corner) to the midpoint of the opposing side, bisecting it.

  • We learned in the previous lesson what the midpoint means for a line.

Every triangle has exactly three medians, one from each vertex, and they all intersect each other at the triangle’s centroid (center of gravity).

Before we can start finding the median of a triangle, you may need to touch up on how to find the slope of a line. It’s important that you watch the next video before you can find the median.

  • If you already familiar with this, you can skip to the next video.
