What are all parallelograms?
Parallelograms are a special form of quadrilaterals (four sided polygons). Parallelograms have 2 sets of parallel sides. So you could say that all parallelograms are quadrilaterals. Or you could say that all parallelograms are polygons. I'm not sure what you are asking.
Do all parallelograms have at least one right angle?
The simple answer is no, not all parallelograms have at least one right angle. However, there are some that do. Rectangles and squares are 'special' parallelograms that all have at least one right angle.
Can a parallelogram be a rectangle and a square?
the three special quadrilaterals that can be a parallelogram are a rectangle, a square, and a rhombus Actually, this is incorrect. All squares are rectangles. All rectangles are parallelograms. Therefore all squares are parallelograms. But not all parallelograms are rectangles. And not all rectangles are squares.
Are all trapezoids parallelograms?
No trapezoids are parallelograms, and no parallelograms are trapezoids.
Are all parallelograms trapezoids?
No trapezoids are parallelograms, and no parallelograms are trapezoids.
