WebIn a rhombus, the diagonals intersect each other at right angles and hence are perpendicular to each other. • A parallelogram has two parallel pairs of opposite sides. A rectangle has two pairs of opposite sides parallel, and four right angles. A rhombus is defined as a parallelogram with four equal sides. WebMar 29, 2024 · As it is rhombus all sides are equal so AB = BC. In ABC. ∠CAB = ∠ ACB = 35° Sum of angles in triangle is 180° ∠CAB + ∠ ACB + ∠ ABC = 180° ∠ABC = 180 ° - 70° = 110°

WebSep 14, 2014 · The fours sides of a rhombus are of equal length. This also means that opposite angles of a rhombus have equal measure. The interior angles add up to 360 because there are four side. (n-2) (180)=Interior Angle; where n=number of sides. So if the opposite angles are equal then if ABC=64, ABD=ABC=64. WebIf perimeter of the rhombus is 40 cm and AC = 16 cm , then the length of BD = A) 8 c m B) 16 cm C) 12 c m D) 24 c m 15. 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 ... flip grid support
