The statement is true . A square has 4 equal sides and facing sides are parallel. A rhombus has one pair of parallel sides only. The other facing pair are unequal and not parallel.All the sides of a square are 90degrees but a rhombus' sides are not 90degrees .
D is the correct answer as both square and parallelogram make up quadrilaterals because they both have four sides and the angles are different .
I do not agree with the statement which has been stated . Parallelograms' sides are parallel while for a square , the sides are equal .
