The coordinates of the vertices of triangle PQS are P(1,5) , Q(4,-1) and S(6,0). (i) Write down the position vectors PQ and PS. (ii) Determine the position vectors OG and OH given that G and H are the midpoints of PQ and PS respectively. (iii) Determine the vectors GH and QS (iv) Hence, stare two geometrical relationships between GH and GS.
.... well XY = a vector from X to Y. .... what do you think PQ is ?
