None
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
It can only have a maximum of one- and that is only if it is a right-angled isosceles triangle. ----------------------------------------------------- Yes not all isosceles triangles are right angle triangles - this is a special case.
A trapezium doES have 4 angles.
It has 1 vertical line of symmetry
Two
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.
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 has 4 right angles...Correction: it has 4 angles but they are not right angles. A structure/shape with 4 right angles is a rectangle or square.
The 4 interior angles add up to 360 degrees
Usually two, but one if it is a right-angled trapezium.
None or two.
Usually none.
A trapezium has two diagonals.
Circle, isosceles,equalateral and scalene triangles, trapezium and many, many more.
Depending upon the trapezium, two or none: ....................................................................... ...------------.............................---------....... ...|.................\........................../..............\...... ...|.......A..........\......................./........B......\..... ...|.....................\..................../..................\.... ...----------------...................---------------... ....................................................................... Trapezium A has two; Trapezium B has none.

None, normally. One if it is an isosceles trapezium.
