Thank you for the opportunity to help you with your question!

parallelogram is a quadrilateral with opposite sides parallel (and therefore opposite angles equal). A quadrilateral with equal sides is called a rhombus, and a parallelogram whose angles are all right angles is called a rectangle.

Please let me know if you need any clarification. I'm always happy to answer your questions.
