Yes... I think so.
If two of the angles of a parallelogram are acute, then the other two angles will be obtuse. Since a parallelogram contains two pairs of parallel sides, both of the acute angles and both of the obtuse angles respectively will measure the same.
a trapezoid :) * * * * * Not necessarily. A trapezoid can have two right angles, one acute and one obtuse angle. A parallelogram which is not a rectangle must have 2 acute and 2 obtuse angles.

Any parallelogram that is not a rectangle or a square must have two obtuse angles (and two acute ones).
Yes, unless it is a rectangle and they are all right angles.

A kite, a parallelogram, many ordinary quadrilaterals with no specific names.
A parallelogram is a quadrilateral with opposite sides parallel and congruent.
the two angles that are wide spread are the obtuse ones. these are angles 91 degrees and through 179 degrees. the two angles that are pinch closer together of the acute ones. these are angles 1 degrees through 89 degrees.
