## 5.3 Medians and Altitudes of Triangles

Median of a triangle- A segment whose endpoints are a vertex of the triangle and the MP of the opposite side.

Centroid of the triangle- Point of concurrency of the medians of a triangle.

Altitude of a triangle- A perpendicular segment from a vertex to the line containing the opposite side.

Orthocenter of a triangle- Point of concurrency

5-3-1 Centroid Theorem - The centroid of a triangle is located ⅔ of the distance from each vertex to the midpoint of the opposite side.
