4. ABC is a triangle and P, Q are the midpoints of AB, AC respectively. If AB = 2x and AC = 2y, express the vectors (i) BC, (ii) PQ, (ii) PC, (iv) BQ in terms of x and y. What can you deduce about the directed line-segments BC and PQ? 4. ABC is a triangle and P, Q are the midpoints of AB, AC respectively.
