What is the definition of an altitude in a triangle?

Back

An altitude of a triangle is a perpendicular segment from a vertex to the line containing the opposite side.

Front

What is the centroid of a triangle?

Back

The centroid is the point where the three medians of a triangle intersect, and it is also the center of mass of the triangle.

What is the relationship between the centroid and the lengths of the segments it creates on the medians?

Back

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