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? 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.
