In a Rhombus Abcd, If ∠Acb = 40°, Then ∠Adb = - Mathematics Shaala…
WebWe know that the diagonals of a rhombus are perpendicular to each other. So, ∠ AOD = 90 ° We also know that the sum of interior angles of a triangle is 180 °. Sum of all angles of a triangle = 180 ° ⇒ ∠ AOD + ∠ ADO + ∠ DAO = 180 ° ⇒ 90 ° + ∠ ADO + 40 ° = 180 ° ⇒ 130 ° + ∠ ADO = 180 ° ⇒ ∠ ADO = 180 ° – 130 ... Web∠ BOC + ∠ ACB + ∠ CBD = 180˚ 90˚ + 40˚ + ∠ CBD = 180˚ ∠ CBD = 180˚ - 30˚ ∠ CBD = 50˚ Now, In Δ BOC and Δ AOD, we get, AD = BC [All sides of rhombus are equal] AO = OC [ Diagonals of a rhombus bisect each other] OD = OB [Diagonals of a rhombus bisect each other] Therefore, Δ BOC and Δ AOD are congruent by SAS congruence.
