A trapezium has 2 obtuse and 2 acute angles.
A trapezium has 4 interior angles that add up to 360 degrees
A trapezium has four vertices.
The interior angles of a trapezium = 360°The British definition of a trapezium is a quadrilateral with one pair of parallel sides.
4 internal angles

A trapezium doES have 4 angles.

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
A trapezium (or trapezoid in American English) typically has two pairs of angles, but only one pair of opposite angles can be equal in size if it is an isosceles trapezium. In a general trapezium, there are no restrictions on the angles, so they can vary widely. Thus, a trapezium does not have to have any angles that are the same size unless specified as isosceles.
