  1. Medians of a Triangle Geometry (Holt 5-3) K.Santos

  2. Median of a triangle Median of a triangle is a segment whose endpoints are a vertex of the triangle and the midpoint of the opposite side.

  3. Centroid of a triangle Centroid of a triangle is the point of concurrency of the medians of the triangle.

  4. Centroid Theorem (5-3-1) The centroid of a triangle is located of the distance form each vertex to the midpoint of the opposite side. B X Y P A C Z AP = AY BP = BZ CP = CX YP = AY ZP = BZ XP = CX

  5. Centroid 2 6 1 3 2 + 1 = 3 6 + 3 = 9 Longer segment reduced is Shorter segment reduced is

  6. Centroid Example B In ABC,G is the centroid. AF = 9 and GE = 2.4. Find each length. E F G Find AG AG = AF A D C AG = (9) AG = 6 Find CE GC = CE and GE = CE 2.4 = CE 7.2 = CE (multiplied by 3)
