Abcd is a parallelogram and line cd = line da. determine whether the parallelogram is a rhombus. if so by which property?
a. rhombus; perpendicular diagonals property, b. rhombus; congruent adjacent sides property, c. rhombus; bisected angles property, d. not a rhombus

Option: B is the correct answer.

    B.  Rhombus; congruent adjacent sides property.

We are given that:

ABCD is a parallelogram ( this means AB||CD and BC||DA ) and line CD = line DA.

Hence,  the parallelogram is a rhombus by:

            Congruent adjacent sides property.
