Medians of a Triangle

Mathematics — Second Preparatory

Medians of a Triangle

Lesson summary

Lesson summary

  • A median joins a vertex to the midpoint of the opposite side. Every triangle has three medians.
  • The three medians meet at the centroid G, which divides each median in the ratio 2 : 1 from the vertex.
  • A median divides the area of a triangle into two equal parts.
  • Centroid coordinates = (sum of the x-coordinates ÷ 3, sum of the y-coordinates ÷ 3).
