point p [4,-4] q [9,6] r [-2,4] find co-ordinates of S where PQRS is a parallelogram?
this is a typical o level exam question so i decided to post it!
LOGIC
S AND QR r diagonals which bisect each other.
METHOD:FIND MID POINT m OF PR
M ---->x-CO-ORDINATE 4+[-2] divided by 2=1 nd Y co-ordinate=-4+4 divide by 2=0
the midpoint of the other diagonal QS will be the same wats left is a piece of cake which idont want to eat now so try to proceed frther and consult me by replyin in case of any ambiguity
