Use midpoint and centroid relationships

A median joins a vertex to the midpoint of the opposite side. The three medians meet at centroid C.

Learning objective

What this activity builds

Distinguish equal side halves from the centroid’s unequal division of a median.

Worked example

A median is 24 units long. How far is its vertex from the centroid, and how far is the centroid from the midpoint?

16 units from vertex to centroid; 8 units from centroid to midpoint.

The centroid divides a median in a 2:1 ratio. One part is 24 ÷ 3 = 8, so the longer segment is 2 × 8 = 16.

Teaching notes

Make the practice count

  • A median joins a vertex to the midpoint of the opposite side.
  • A midpoint divides a side into equal halves.
  • Along a median, the vertex-to-centroid segment is twice the centroid-to-midpoint segment.
