List the properties that all rhombuses share.

All rhombuses share the same properties as parallelograms. Also the diagonals bisect the angles and are perpendicular bisectors of each other.

Step-by-step explanation:

The propperties of parallelograms (also shared by rhombuses) are:

It is a quadrilateral: it has four vertices, four sides and four interior angles. Opposite sides of a parallelogram are parallel. Opposite sides are of equal length (congruent). The internal angles at any two adjacent vertices are supplementary (total 180 °) Opposite internal angles are equal in measure.

Special properties of rhombuses:

Diagonals bisect the angles: the diagonal matches its bisector and divides the angles in half. Diagonals are perpendicular: the intersection of both diagonals shows four right angles.
