more than one answer

All of the options are the answer. : )

Answer: Technically all of these things could have four right angles.

Step-by-step explanation: A parallelogram has to have two sides that line up, so it could be like a square or a rectangle (which bot have four right angles). In the dictionary, it states a Rhombus as a parallelogram with opposite equal acute angles, opposite equal obtuse angles, and four equal sides or any parallelogram with equal sides, including a square, SO a rhombus is also correct.
