In quadrilateral ABCD of the given figure, X andY are points on diagonal AC such that AX = CY andBXDY is a parallelogram. Show that ABCD is a parallelogram. |

Answer» Step-by-step EXPLANATION: We have, BXDY is a parallelogram. Therefore the diagonals bisect each other =>BO=DO, XO=YO............. (1) Given, AX=CY. ADDING xo on both sides, we get, AX+XO=CY+YO.......... from 1 we have XO=YO AO=CO. SINCE AO=CO, BO=DO, therefore the diagonals bisect each other Or, ABCD is a parallelogram |
