What else can I help you with?
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
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.
A quadrilateral with diagonals and no right angles?
A parallelogram is one of them.
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
Which quadrilateral has 4 congruent sides and 4 right angles?
A SQUARE is the only one that satisfies the conditions.
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.
Can a quadrilateral have three acute angles and one right angle?

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.
Quadrilateral with one pair of equal angles and your diagonals intersect at right angles?
Rhombus rhombus
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
