What is the relationship between the centroid and the medians?

Back

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

What is the significance of the circumcenter?

Back

The circumcenter is equidistant from all three vertices of the triangle, making it the center of the circumcircle.
