In a rhombus abcd angle a 60
Did you know?
WebABCD is a rectangle and diagonals of a rectangle are equal and bisect each other. OA = OD ⇒ ∠ODA = ∠DAO (angles opposte to equal sides are equal) ⇒ ∠ODA = 55° In DODA, by angle sum property, ∠ODA + ∠DAO + ∠AOD = 180° ⇒ 55° + ∠55° + ∠AOD = 180° ⇒ ∠AOD = 70° Solution 10 Solution 11 Solution 12 Solution 13 Correct option: (c) 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. …
WebBecause you could have a rhombus like this that comes in where the angles aren't 90 degrees. But all squares are rhombuses, because all squares, they have 90-degree angles … WebAug 29, 2024 · Since the rhombus has angles that measure 120 and 60 degrees, we see that when they are bisected, they become 60 and 30 degrees, respectively. Therefore, each of …
WebIt would only work if the shape was a square (or a rhombus), and in your case, it isn't. The answer your method yields is 170, which is incorrect. The correct answer is 150. Simply … Web1.

There is not enough information given to determine the measure of angle BDE. 2. Two prime numbers are randomly selected without replacement from among the first eight prime numbers.
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.
WebIf ∠ D A B = ∠ D C B = 60 ° than The triangles D A B and D C B are equilateral, so ∠ A D B = 60 °.
