No, a hexagon is not a parallelogram. A parallelogram is a four-sided closed plane figure with both pairs of opposite sides parallel to each other. A hexagon is a six-sided figure.
A parallelogram is a quadrilateral. There are many different types of parallelograms. A rectangle, a square and a rhombus are all examples of parallelograms. The opposite angles of a parallelogram are always equal. Both pairs of opposite sides are also equal. Adjacent angles of a parallelogram always add up to 180 degrees. The sum of all four angles of a parallelogram is always 360 degrees.
A hexagon has six equal sides and six equal angles. Each angle of a hexagon is 120 degrees, and the sum of all six angles is 720 degrees.
