Prove that if the diagonals of a parallelogram are perpendicular, then ...
WebA 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 ... WebLet ABCD be the given parallelogram. Consider ΔAOD and ΔCOD . Since adjacent sides of the parallelogram are equal, we can conclude that all four sides are equal. Hence, a … WebJul 8, 2024 · The diagonals bisect the angles. The diagonals are perpendicular bisectors of each other. The rectangle has the following properties: All of the properties of a parallelogram apply (the ones that matter here are parallel sides, opposite sides are congruent, and diagonals bisect each other). All angles are right angles by definition. graham thompson facebook
