1. Use the point and segment tools to construct a triangle;
2. Use the midpoint tool to determine the midpoint of a segment,
1. What if the point was used to draw points D and E instead of the midpoint tool?
How will this affect the figure when you drag the other points?
2. Try dragging points D and E. What do you observe? Justify your answer.
3. Try dragging points A, B, and C. What do you observe? How do they affect points D and E?
