3. State thoroughly and precisely Euclids fifth postulate.
According to Playfair, "Given a line l and a point P not on l, there is exactly one line through P that is parallel to l"
Are Euclids fifth postulate and Playfair's claim logically equivalent? If yes, justify your stance. If no, produce a counter example.

Let L be the line passing through the point P=(−3, −4, 2) with direction vector →d=[−3, 3, 0]T. Find the shortest distance d from the point P0=(1, −5, −1) to L, and the point Q on L that is closest to P0. Use the square root symbol '√' where needed to give an exact value for your answer. d = 0 Q = (0, 0, 0)
