It goes above and beyond that to also have four equal-length sides, but it is still a type of parallelogram. This kind of diamond is 3-Dimensional, so it would be a polyhedron, not a polygon. The Hexahedron is one of the five Platonic Shapes, which are well-known aspects of sacred geometry. So a rhombus by definition, the four sides are going to be equal. A more flexible definition of shape takes into consideration the fact that realistic shapes are often deformable, e.g. Step 3: Area of the diamond = 84 cm2, Identifying-and-Locating-Ordered-Pairs-Gr-5, Reading-and-Writing-Decimals-to-Thousandths-Gr-5.
