Medians and Altitudes of Triangles

Front

What is a median of a triangle?

Back

A median of a triangle is a segment whose endpoints are a vertex of the triangle and the midpoint of the opposite side.

Front

What is an altitude of 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 of a triangle is the point where the three medians are concurrent.

What does the Centroid Theorem state?

Back

The Centroid Theorem states that the centroid of a triangle is located 2/3 of the distance from each vertex to the midpoint of the opposite side.

What is the relationship between medians and centroids in a triangle?

Back

The centroid divides each median into two segments, with the longer segment being twice the length of the shorter segment.

What is the significance of the orthocenter in a triangle?

Back

The orthocenter is significant as it helps in understanding the triangle's altitudes and their concurrency.
