No. A trapezoid need not have any right angles.
A trapezoid can't have three right angles. A quadrilateral with three right angles must have a total of four right angles, since a quadrilateral's interior angles add up to 360. 360 - (3*90) = 90, so the fourth angle would have to be right as well. A quadrilateral with four right angles is not a trapezoid; instead it is a rectangle or a square.
yes it can
no
It has no right angles. It has two acute angles.
0 or 2.
There are obtuse, acute, and right angles. It depends on what type.
It can have 2 right angles but normally none unless it is an isosceles trapezoid in which case it will have 2 pairs of congruent base angles

Yes, a trapezoid can have 3 right angles.
Every Trapezoid has 4 angles.An isosceles trapezoid has 2 acute angles.?
