Best ResponseYou've already chosen the best response.0Sorry. What's "Trisects", "Diagonal" and "Midpoint" in this situation? Definitions are always different for different questions.

Best ResponseYou've already chosen the best response.0Trisects  divided equally in 3 parts. Diagonal  from one corner to the opposite. Mid point  midway. Fairly basic.

Best ResponseYou've already chosen the best response.0Maybe its trisecting the parallelogram itself? Not sure. What course is this? Vectors?
