The 4 interior angles of a trapezium add up to 360 degrees and if it's an isosceles trapezium it can have 2 equal obtuse angles and 2 equal acute angles
One and the two others are acute angles
A quadrilateral kite can have two obtuse angles and two acute angles that add up to 360 degrees.

The simple diamond shaped: - - - - - - - - has 2 acute angles and 2 obtuse angles! :P
A trapezium has 2 obtuse and 2 acute angles.
a trapezium has two obtuse angles or one if it has a right angle
A trapezium has one or two obtuse angles.
There can be 10 obtuse angles. If there are no reflex angles there can by up to three acute angles (I think).
2
Usually two, but one if it is a right-angled trapezium.
It can have 0 or 2 right angles, 1 or 2 acute or obtuse angles.
One and the two others are acute angles
None. Though there can be ten if the hexagons are concave hexagons.
It has 2 equal opposite acute angles and 2 equal opposite obtuse angles and the 4 angles add up to 360 degrees
None. An acute triangle is one in which all angles are acute. An obtuse triangle is one in which one of the angles is obtuse. A right angled triangle is one in which one angle is a right angle (90o)
A rhombus will either have four right angles, or two acute angles and two obtuse angles.
