Question 1.
Show that the lines x−1/ 2 = y−2/ 3 = z−3/ 4 and x−4/ 5 = y−1/ 2 = z, intersects. Find their point of intersection.
Solution:
It is clear from above that both lines intersect each other and the coordinates of point of intersection are (-1, -1, -1).
Question 2.
Check, whether following lines intersect or not
Solution:
Question 3.
