Can a quadrilateral be a parallelogram and a rhombus?
Yes. All rhombuses are parallelograms, but the reverse is not true. (I.e. there are parallelograms which are rhombuses and there a parallelograms that are not rhombuses. -- Just like Every bus has wheels but not everything with wheels is a bus.)
Are parallelograms and rhombus the same think?
No. All rhombi (rhombuses) are parallelograms but all parallelograms are not rhombi.
What shapes are also parallelograms?
squares, rectangles, rhombuses
Which three quadrilaterals have obtuse angles?
parallelograms, rhombuses, & hexagons
There are some parallelograms which are not rectangles true or false?
yes. rectangles are just the special cases of parallelograms where the angles are all 900

Are parallelograms rhombuses?
Some parallelograms are rhombuses, but all rhombuses are parallelograms. A parallelogram is a rhombus if and only if all of it's sides are the same length.
What parallelograms are not rectangles?
rhombuses
What quadrilateral has opposite sides that are congruent?
That would be a parallelogram. (Rectangles, Squares and Rhombuses are special types of parallelograms.)
Are all rhombuses also rectangles?
No. Rhombuses that are also rectangles are called squares. Rhombuses are parallelograms with 4 equal sides, while rectangles are parallelograms where all the angles are right.
Are parallelograms and rhombus the same think?
No. All rhombi (rhombuses) are parallelograms but all parallelograms are not rhombi.
Can some rhombuses be parallelograms?
Some rhombuses can be parallelograms. It all depends on the direction of the sides. A diamond is a rhombus that is not a parallelogram A square is a rhombus that is a parallelogram
Why are all squares rhombuses?
Are all rectangles parallelograms
What shapes are also parallelograms?
squares, rectangles, rhombuses
What parallelograms don't have right angles?
Rhombi (or rhombuses)
Some parallelograms are squares?
By definition, all squares are parallelograms. Not all parallelograms, however, are squares. All rectangles and rhombuses are also parallelograms.
Which three quadrilaterals have obtuse angles?
parallelograms, rhombuses, & hexagons
