If a rhombus is a square, all four of its angles are right.
Otherwise, all angles are either acute or obtuse, but not right.

#### Explanation:

As a parallelogram, rhombus has a sum of two interior angles that share a side equal to ${180}^{\circ}$.
Therefore, only if all angles are equal, they all are equal to ${90}^{\circ}$.
That equality of all angles makes a square out of rhombus.
