Front

What is the relationship between the lengths of the segments created by the centroid on a median?

Back

The centroid divides each median into two segments, with the segment connecting the vertex to the centroid being twice as long as the segment connecting the centroid to the midpoint.

Back

A segment from a vertex perpendicular to the line containing the opposite side.

Front

What is the difference between a median and an altitude in a triangle?

Back
