Medians and Centroid of a Triangle

1. Determine if points D, E, F are midpoints. Take a snapshot of the measures to support your answer. 2. Name the three medians of the triangle. 3. Name the point were the three medians meet. Which point of concurrency is it? 4. Find the following measures: AG = ________ CG = ____________ BG = ______________ GD = ________ GF = ____________ GE = ______________ AD = ________ CF = ____________ BE = ______________ 5. Determine the following ratios: AG to AD: ________ CG to CF: __________ BG to BE: ____________ GD to AD: _________ GF to CF: __________ GE to BE: ____________ 6. What conclusions can we make about the centroid?
