One quadrilateral that has no right angles and no parallel sides is a?
It's a quadrilateral. There's no other name for it.
What is the name for a quadrilateral with one pair of parallel sides but no right angles?
rhombus
A quadrilateral with diagonals and no right angles?
A parallelogram is one of them.
Can a quadrilateral have three acute angles and one right angle?
No, a quadrilateral can't have three acute angles and one right angle. The angles of a quadrilateral must total 360. The three other angles of a quadrilateral with one right angle would then have to total 270 degrees. If all three were acute (less than 90 degrees), they could not total 270.
Is a quadrilateral with one right angle necessarily a rectangle?
A quadrilateral can have two right angles and still not be a rectangle, if one side is oblique (neither right nor parallel) to the others, but three right angles force the fourth, and you have a rectangle.
One quadrilateral that has no right angles and no parallel sides is a?
It's a quadrilateral. There's no other name for it.
What is a quadrilateral that is not a rectangle?
Any quadrilateral in which at least one (and therefore at least two) angles are not right angles is not a rectangle. The majority of these do not have a specific name.
What is the name for a quadrilateral with one pair of parallel sides but no right angles?
rhombus
What is a Quadrilateral with two sets of parallel sides?
It is a parallelogramIf one of the angles is a right angle (then they all are) and the quadrilateral is a rectangle.If both pairs of sides are equal in length (but none of the angles is a right angle) the quadrilateral is a rhombus.If the sides are equal and one of the angles is a right angle, the quadrilateral is a square.

Quadrilateral with one pair of equal angles and your diagonals intersect at right angles?
Rhombus rhombus
What is a quadrilateral that has one pair of parallel sides and two right angles?
That would be a trapezoid. A trapezoid does not have to have two right angles it only needs to have two parallel sides. There is not a name for the exact quadrilateral you are looking for but the shape is still within the definition of a trapezoid.
Does all Quadrilaterals have at least one right angles?
No, a quadrilateral does not necessarily have any right angles. If it has a right angle, it will necessarily have four right angles, and will be a rectangle. But not all quadrilaterals are rectangles. As long as a polygon has four sides, it is a quadrilateral. It might have, for example, two angles of 100o and two angles of 80o.
Do all irregular quadrilateral have no right angles?
No, some may
Are all quadrilaterals cyclic quadrilaterals?
No, one example is a kite that DOES NOT have two right angles. It is not a cyclic quadrilateral. A kite that does have two right angles is one.
