No, not in plane (Euclidean) geometry. But on the surface of a sphere, a quadrilateral bounded by 2 sets of great circles [one set has its intersecting points at what would be the 'poles', and the other set has its intersecting points on opposite sides of what would be the 'equator'] will have 4 acute interior angles.
Yes as for example a rhombus is a 4 sided quadrilateral that has 2 equal opposite acute angles and 2 equal opposite obtuse angle and the 4 angles add up to 360 degrees.
There can be 4 different acute angles in an irregular 4 sided quadrilateral that all add up to 360 degrees.
It is a rhombus which also has 2 acute angles
a rectangle has 4 right angles, a parallelogram has 2 acute angles and 2 obtuse angles
There's no general rule. The only thing you can say about the angles ina quadrilateral is that all 4 of them always add up to 360 degrees.

No because the 4 interior angles of a 4 sided quadrilateral must add up to exactly 360 degrees.
A quadrilateral can have 0 to 3 acute angles, but never 4:A rectangle and a square are both quadrilaterals with four right angles, hence they have no acute angles.A kite-shaped figure can have one acute and three obtuse angles, or three acute and one obtuse angles.A parallelogram and a rhombus have two acute and two obtuse angles.The sum of the interior angles of any quadrilateral is 360º; thus it would be impossible for all angles to be acute (less than 90º each)
Impossible. You cannot have an obtuse angle without an acute angle in a quadrilateral.
No, because it is a quadrilateral and all the angles have to add up to 360 degrees and the less possible degree and angle could have would be 90 so, parallelograms can only have 2 acute and 2 obtuse angles.
A rhombus is a 4 equal sided quadrilateral with equal opposite acute angles and equal opposite obtuse angles with diagonals that bisect each other at right angles.
It is a rhombus which also has 2 acute angles
With 2 acute and 2 obtuse angles it has 4 angles - the shape is a quadrilateral. The shape can be one of trapezium, parallelogram, rhombus, kite or a general quadrilateral. With the two acute angles next to each other (forcing the two obtuse angles to be next to each other) the shape can be either a trapezium or a general quadrilateral.
A rhombus
NO!!! All four angles are right-angles (90 degrees) The word 'rectangle' means -right-angled quadrilateral.
a rectangle has 4 right angles, a parallelogram has 2 acute angles and 2 obtuse angles
