Answer:
(a) Yes.
(b) No.
Step-by-step explanation:
Yes, a rhombus is a parallelogram. A rhombus is a quadrilateral with four sides of equal length and opposite sides that are parallel. This fits the definition of a parallelogram, which is a quadrilateral with opposite sides that are parallel.
No, a rhombus is not always a square. However, every square is also a rhombus. This is because while all the sides of a rhombus are the same length, it is not guaranteed that all of the angles will be 90 degrees.
