1. Chapter 5 Medians of a Triangle

2. Median of a triangle Starts at a vertex and divides a side into two congruent segments (midpoint).

3. Centroid of the triangle The point of concurrency of the three medians of a triangle. Always lies inside the triangle!

4. B C A Always Inside!

5. Median formula The medians of a triangle intersect at a point that is in a 2:1 ratio. –F–From vertex to centroid=2 –C–Centroid to side=1

6. P is the centroid of triangle ABC D B C A P F E 6 3 2 4 If EC = 12, EP = ___ and PC = ___ 4 8
