Yes, a parallelogram has opposite sides that are equal in length. This is one of the defining properties of parallelograms, along with having opposite angles that are equal and the diagonals bisecting each other. Therefore, in a parallelogram, if one pair of opposite sides is known to be equal, the other pair will also be equal.
