Question 515768: Hello. I have a problem saying that the points T(2,1), U(4,5), and V(7,4) are all the midpoints of a triangle. The first thing that i have to do is that i have to plot the midsegments of that triangle with those midpoints, which i understand how to do (you just plot those points and connect them). Then the problem tells me to draw the original triangle and give the coordinates of each vertex. I have already drawn the original triangle because i know that the original sides are parallel to the midsegments, but i do not understand how to find the coordinates of each vertex. Could you please help me with this?
