Four 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.
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.
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.
that's a rhombus with no right angle
