Prove that the diagonals in a parallelogram
Webb3 dec. 2015 · 2 Answers. If you have already proven this theorem, you can reference it and it is a fine proof. If you have not already proven it, you need to do so. By cutting the parallelogram into four triangles by the diagonals and showing that the triangles are congruent if the diagonals are, you can get there. There are other approaches as well.

WebbA O = C O (Diagonals of a parallelogram bisect each other) ∠ A O D = ∠ C O D = 90 ∘. D O = D O. ∴ Δ A O D ≅ Δ C O D [SAS congruency rule] A D = C D [CPCT] Since adjacent sides of the parallelogram are equal, we can conclude that all four sides are equal. Hence, a parallelogram whose diagonals are perpendicular to each other is a ...
