Best ResponseYou've already chosen the best response.0Let's assume that the diagonals of a parallelogram do not bisect one another. A parallelogram has four sides and it's opposite angles and opposite sides are congruent and parallel. If the diagonals of a parallelogram intersect each other, and a parallelogram's opposite angles and opposite sides are congruent and parallel, then the intersecting diagonals must also bisect one another.

Best ResponseYou've already chosen the best response.0I rather not use someone else's work and claim it as my own. I just want to know if this is correct and if not, then if I could get a few tips and hints that can help me.

Best ResponseYou've already chosen the best response.0Let ABCD is a parallelogram. By definition, ABCD is a nonself intersect quadrilateral, hence its diagonals intersect. Let O is the intersection point of the diagonals. We need prove OA = OC and OB= OD to show that the diagonals are bisect. Prove OA =OC consider \(\triangle AOD ~~and ~~\triangle BOC\) we have \(\angle O_1 =\angle O_2\) (vertical opposite angles) \(\angle A_1=\angle C_1\) (alternate exterior angles) \(\angle B_1=\angle D_1\) (alternate exterior angles) Hence \(\triangle AOD = \triangle BOC\) (AAA case) \(\implies OA = OC \)

Best ResponseYou've already chosen the best response.0Do the same with OB and OD then conclude that the diagonals are bisect.
