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.

Parallelograms have 2 acute and 2 obtuse angles, or 4 right angles in the case of a rectangle. But either way, the max number of acute angles is 2 and the minimum is zero. Remember acute angles is less than 90 degrees so in a square or rectangle, which is a parallelogram since it has two sets of parallel sides, there are NO acute angles. So the answer to the question is..it depends, but no more than two for sure.

A kite, a parallelogram, many ordinary quadrilaterals with no specific names.
A parallelogram is a quadrilateral with opposite sides parallel and congruent.
