Customize this worksheetA median joins a vertex to the midpoint of the opposite side. The three medians meet at centroid C.
Learning objective
Distinguish equal side halves from the centroid’s unequal division of a median.
Worked example
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.
