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. WebJan 10, 2024 · There are three useful formulas for the calculation of the area of the rhombus: Knowing base and height: area = base × height Knowing the diagonals of a rhombus: area = (e × f)/2 Knowing the side s and any (!) angle: area = s² × sin (angle) Why can we use any angle in the last rhombus area formula?

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 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 °. Let O the center of the circle, than the radius of the circle is r = A O sin 60 ° = 3 2 and the … did arthur leonard schawlow win a nobel prize

Quadrilateral ABDE is a rhombus. The measure of angle ABF …

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 … WebAll of the interior angles of the rhombus are degrees. Correct answer: Both of the remaining angles are degrees. Explanation: The four interior angles in any rhombus must have a sum of degrees. The opposite interior angles must be equivalent, and the adjacent angles have a sum of degrees.
