Every rectangle is a quadrilateral and a parallelogram
Yes. All rectangles are also parallelograms, but not all parallelograms are rectangles.
Some parallelograms are rectangles; all rectangles are parallelograms.
Here's something to think about: -- Every rectangle is a parallelogram. There are an infinite number of them. -- There are also an infinite number of more parallelograms that are not rectangles.
It's not possible to have all sides parallel. The quadrilaterals that have every side parallel to the one opposite it ... or two pairs of parallel sides ... are: -- parallelograms -- rhombera -- rectangles -- squares Notice that -- every square is also a rectangle, a rhombus, and a parallelogram. -- every rectangle is also a parallelogram. -- every rhombus is also a parallelogram.
No. Most parallelograms are not rectangles. But every rectangle is a parallelogram.

no because it is a Parallelogram^That is quite an incorrect answer. Rectangles are parallelograms, but a parallelogram may not be a rectangle.All rectangles have 4 corners.Besides the point, to the original answerer, all parallelograms also have 4 corners...
No, as the angles of a square are all equal, whereas the angles of a parallelogram typically aren't. There are other examples, as well; this is just one difference.
All rectangles are also parallelograms. A parallelogram needs four 90-degree angles to be a rectangle
Parallelogram (if it is a rectangle), Rectangles and Rhombuses (if they are not also a square)
This is false. Every rectangle is a parallelogram, but the converse (your statement) is not true. Imagine the set of all quadrilaterals (4 sided polygons). Within that set would be sets of kites, parallelograms, and other quadrilaterals. Within the parallelogram set, would be rectangles, rhombuses and other parallelograms. Then if a rhombus is also a rectangle, it would be a square, that would be the intersection of the set of rectangles and set of rhombuses. Hope this helps.
All rectangles are also categorized as parallelograms. If a parallelogram has one of its angles equal 90°, then all four angles are 90° and it is a rectangle.
