essay question
1 answer
A rhombus is a quadrilateral with all four sides equal in length and opposite sides parallel. This means that the angles opposite each other are also equal. Therefore, in the rhombus ABCD, angles ABC and CDA are equal, so the sides opposite them (AB and CD) must also be equal. This is why ABC = CDA.
