trapezoid
Parallelogram.
It is a parallelogram.
They will be acute angles.
No shape does. If it has 4 sides and one pair of parallel lines it cannot have only 1 right angle, it must either have: 1) 2 right angles, 1 acute acute and 1 obtuse angle; or 2) no right angles, 2 acute angles and 2 obtuse angles; in which case it would be a trapezium (trapezoid).
There can be 10 obtuse angles. If there are no reflex angles there can by up to three acute angles (I think).

parallelogram
A polygon with two acute angles, two obtuse angles, and two pairs of parallel sides is known as a trapezoid (or trapezium in some regions). Specifically, it can be classified as an irregular trapezoid, where one pair of opposite sides is parallel, and the angles vary in measure. This configuration allows for the presence of both acute and obtuse angles while maintaining the parallel sides characteristic of trapezoids.
A square
Parallelogram.
Angles are usually illustrated as two acute and two obtuse, but there can be two right, one acute and one obtuse. Angles cannot be parallel since that is a characteristic of lines, not angles!
No, a trapezoid does not have four obtuse angles. A trapezoid has one pair of parallel sides and the other pair of non-parallel sides. The angles of a trapezoid can be a combination of acute, obtuse, and right angles, but it cannot have four obtuse angles.
A rhombus (pushed over square) will give you 2 pairs of parallel, congruent sides, 2 acute angles and 2 obtuse angles.

polygon
A triangle having all angles less than 90 degrees is a polygon having no parallel sides and all acute angles.
