Question

If lines l || m || n, what can you say about the line the lines l and n​

Answer 1

Answer:

Lines l and m are parallel to each other, hence they are making an angle of 00 between them. 

Similarly, lines m and n are parallel to each other, hence they are making an angle of 00 between them.

Therefore, angle between lines l and n is also 00, which proves that l∥n.
