Question

ABCD is a parallogram in which coordinate of point A(3,1),B(0,-2),C(1,1).find the coordinate of D.

Answer 1

opposite sides of parrallogram are equal so , first find AB and equate it to CD . As we know the coordinates of C we will easily get the coordinates of D .

after we find the distance of AB . We equate it to CD and divide C by AB and u will get the coordinates of D
