Using the properties listed above, we can conclude that ∠AOB is …
Class 9 NCERT Solutions Maths Chapter 8 - Quadrilaterals
WebApr 15, 2024 · Explanation: ∠C = 31 opposite angles of a rhombus are equal. So, ∠BCO = 15.5 diagonals bisect vertices. ∠BOC = 90 diagonals bisect each other at right-angles. … Web1. Quadrilateral ABDE is a rhombus. The measure of angle ABF is 23˚. What is the measure of angle BDE? F E A D B a. 134˚ b. 164˚ c. 67˚ d. 46˚ e. There is not enough information … curly arrow svg free
in a rhombus ABCD, angle ABC = 64 degrees. calculate angle BCD, angle …
WebCorrect option is B) Using the formula sin90 ∘AB = sin30 ∘OB where O is the centre of rhombus and we know that diagonal of rhombus bisect each other at right angles. AB=6cm OB=OD= two segments of diagonal BD bisected by O. ∠A=60 ∘ ∴∠OAB= 260 ∘=30 ∘ … WebHow does this rhombus calculator work? Depending on the figures you know this rhombus calculator can perform the following calculations: If Angle (A) is given then the other 3 angles will be computed: B = 180° - A C = A D = B The same goes in case Angle (B) is given: A = 180° - B C = A D = B WebBC = AB (side of a rhombus are equal to each other) 1 = 2 (angles opposite to equal sides of a triangle are equal) But 1 = 3 (alternate interior angles for parallel lines AB and CD) 2 = 3 So, AC bisects C. Also, 2 = 4 (alternate interior angles for lines BC and DA) 1 = 4 So, AC bisects A Similarly, we can prove that BD bisects B and D as well. curly arrow transparent background
