Is a parallelograms adjacents sides equal?

In a parallelogram, adjacent sides are not equal; rather, opposite sides are equal in length. This means that if one pair of opposite sides is equal, the other pair will also be equal, but the adjacent sides can be of different lengths. For example, in a rectangle (which is a type of parallelogram), adjacent sides can be unequal, while in a rhombus, all sides are equal.
