Question

the extremities of the diagonal of a parallelogram are the
points (3,-4) and (-6,5) if the third vertex is the point (-2,1),
then find the coordinates of the third vertex

Biju · Answer

fourth vertex = 3 + (-6) - (-2) , (-4) + 5 - 1
= -1, 0

the extremities of the diagonal of a parallelogram are the points (3,-4) and (-6,5). if the third vertex is the point (-2,1), then find the coordinates of the third vertex
