A trapezium (or trapezoid in North America) does not necessarily have any right angles. The only requirement is that it is a quadrilateral (4 sided polygon) with one pair of parallel sides.
If one of the sides is perpendicular to the bottom base, then it is also perpendicular to the top (so 2 right angles). If the other side is also perpendicular to the bottom base then it will be perpendicular to the top base as well, then it is a rectangle, with four right angles.

How many obtuse angles has a trapezium?
Well, honey, a trapezium can have 0, 1, or 2 obtuse angles. It all depends on the specific shape of the trapezium. So, you might want to whip out that protractor and start measuring those angles if you're curious.
How many obtuse angles does a trapezium have?
A trapezium has 2 obtuse and 2 acute angles.
How many angles are in a trapezium?
The interior angles of a trapezium = 360°The British definition of a trapezium is a quadrilateral with one pair of parallel sides.
Does a trapezium have 4 right angles?
No, because it would then be a rectangle.
What quadrilateral has no right angles?
A parallelogram, a rhombus, kites, arrowheads, trapezium and irregular quadrilaterals. However, some kites, arrowheads, trapezium and irregular quadrilaterals can have one (or more) right angles.
