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.
It is a trapezoid that can have two right angles plus one obtuse angle plus one acute angle and the four angles add up to 360 degrees.
It is not possible to have a quadrilateral with four parallel sides - this would bea series of four parallel lines that do not intersect.A quadrilateral with four sides of equal length is a rhombus, however.And a quadrilateral with 2 pairs of parallel sides is a parallelogram.
A quadrilateral has 4 sides, 2 in which never intersect. Therefore, the lines that don't intersect are called parallel. There are 4 parallel sides but has 2 pairs of parallel sides.
Irregular Rhombus
Yes
How about a kite which is a 4 sided quadrilateral that can have 2 equal opposite obtuse angles
A general quadrilateral or a kite.
A right angle trapezoid has 2 right angles, an acute angle and an obtuse angle It has a pair of opposite parallel sides of different lengths The 4 interior angles add up to 360 degrees

The only shapes that fit that description would be a rectangle or a square.Improved Answer:-A trapezoid could have two right angles, an acute angle and an obtuse angle with a pair of parallel sides.
A parallelogram is a quadrilateral with opposite sides parallel and congruent.
A quadrilateral with 3 acute angles and 1 obtuse angle is known as a scalene trapezoid. In this type of quadrilateral, three of the angles are less than 90 degrees (acute angles), while one angle is greater than 90 degrees (obtuse angle). The sides of a scalene trapezoid are of different lengths, and the opposite sides are not parallel. This distinguishes it from other types of quadrilaterals such as rectangles or parallelograms.
It is a 4 equal sided quadrilateral It has 2 equal opposite acute and 2 equal opposite obtuse angle Its opposite sides are parallel
Not sure what the question means. A triangle or quadrilateral may but need not contain an obtuse angle. A pentagon or any polygon with more sides must contain at least one obtuse angle.
That would be a parallelogram.
