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.
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.
A trapezium has 2 obtuse and 2 acute angles.
The interior angles of a trapezium = 360°The British definition of a trapezium is a quadrilateral with one pair of parallel sides.
A trapezium has no right angles therefore there are no perpendicular lines. If it had perpendicular lines, it would be a square or rectangle.
No, because it would then be a rectangle.
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.
A trapezium can have either no right angles or exactly 2 right angles: ...................................... ......------.........---------...... ..../........\.......|..........\..... .../..........\......|...........\.... ../............\.....|............\... ..-------------.....------------... ....................................... Are two trapezia: the first has no right angles, the second has 2.
Usually two, but one if it is a right-angled trapezium.
None or two.
None
Usually none.
A right trapezium. A right trapezium. A right trapezium. A right trapezium.
yes it is A trapizium has no right angles therefore there are no perpendicular.* * * * *Nonsense! A trapezium can have two adjacent angles which are right angles.
A trapezium can have right angles as long as there is at least one pair of parallel lines.
Depending upon the trapezium, two or none: ....................................................................... ...------------.............................---------....... ...|.................\........................../..............\...... ...|.......A..........\......................./........B......\..... ...|.....................\..................../..................\.... ...----------------...................---------------... ....................................................................... Trapezium A has two; Trapezium B has none.
A Trapezium have 2 equal angles.
None or 2, depending upon the trapezium.
