1. 5-2 Medians and Altitudes of Triangles
Vocab:
Median: A segment with endpoints being a vertex of a triangle and the midpoint of the opposite side
Centroid: The point of concurrency of the medians of a triangle
Altitude: A segment from a vertex of a triangle to the line containing the opposite side and perpendicular to the line containing the side
Orthocenter: The point of concurrency of the altitudes of a triangle
Incenter: The point in a triangle equidistant from each side

2. Identifying Medians and Altitudes
Ex 1: Identify a median and an altitude

3. The Centroid Theorem
The centroid is 2/3 of the distance from each vertex to the midpoint on the opposite side
Ex 2: In △ABC, U is the centroid and BU = 16. Find UK and BK.

4. Using the Centroid Theorem
Ex 3: In △ABC, AU = 16, BU = 12, and CF = 18. Find each interior measure.
