A rhombus is a parallelogram because it has 2 sets of parallel sides. A parallelogram does not have to have 4 congruent sides. A parallelogram is not necessarily a rhombus. So, it would be a square and a rhombus.
Not in general, but a rhombus is always a parallelogram.
A parallelogram is a quadrilateral that has two pairs of parallel sides. Some parallelograms, such as squares and rectangles have right angles, but most do not. So the answer is a parallelograms that is not a rectangle (square).
Any parralellogram that's not a rectangle.
a crescent has 19 sides
10 sides.
There is no formula for how many sides there are in a polygon; the name of the polygon shows how many sides it has.
No. But a square is a type of parallelogram. A parallelogram is any quadrilateral that has two pairs of opposite parallel sides. Since opposite sides of a square are parallel, a square fits the definition. I had a teacher who used to say it like this. Think of a square as being a specific animal, say a dog and a parallelogram as a category of animals that your animal fits into, like mammals. You can say that all squares are parallelograms just like you can say all dogs are mammals. But not all mammals are dogs.
