Find points L, M, and N such that the three Cevian lines are mutually parallel. (Use the Parallel Line tool to make sure the lines are exactly parallel, not just approximately parallel.) What is d equal to in this case? How many of the points L, M, and N lie on triangle ABC?
Solution:
In this case, d=1 and only one of the points lie on the triangle ABC.
