Which property is true all for all trapezoids? If the angles of the rhombus are all 90 degrees, then it is a square. A tessellation made out of rhombi is called a rhombille tiling. In short, a rhombus can be defined as a special case of the parallelogram, one in which all 4 sides have the same length. Therefore rhombus is also a parallelogram and features all parallelogram properties. Wiki User Answered . (Note that this parallelogram does not come close to resembling a rectangle of a rhombus.) Top Answer. The third major property of a rhombus has to do with its diagonals. We can prove this with the following: So we have just proven that the diagonals of a rhombus bisect the opposite angles. You could just sketch one (as in the above figure) and run through all things that might be properties. AB = BC = CD = DA. We cover everything from solar power cell technology to climate change to cancer research. Pair of opposite angles in a rhombus are congruent, meaning that they are of equal measure.
