Medians and Centroid of a Triangle 2
In this activity, you will discovery the properties of median and the properties of the point of concurrency of the three medians of a triangle.
Use the Applet to answer the questions below.
1. Determine if points D, E, F are midpoints. Explain.
2. Name the three medians of the triangle.
3. Name the point were the three medians meet. Which point of concurrency is it?
4. Choose a set triangle ABC. Take a screen capture of the image. What are 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?
