AA1 and BB1 are the heights of the trapezoid on the OS base=> Point M lies in the IY quarter and has coordinates: along the OY axis -> y M= AA12 < 0 along the OX axis -> x M= 0 + OA12 > 0 Point N is also in the IY quarter respectively: along the OY axis -> y N= BB12= AA12 < 0 along the OX axis -> x N= OC - B1C2 The assignment does not say that OA= BC. The height of OABC is also not specified. Length MN= OC + AB 2= 10 + 6 2= 8 It follows that OA1 + B1C= 10 - 6= 4 The exact coordinates of M and N cannot be determined more precisely from the given data.
