A right angled triangle or a trapezium* * * * *A trapezium cannot have one right angle. If it has one it MUST have two.
A scalene triangle would fit the given description
a diamond does. There are two obtuse angles in it.
It is any one of the four vertices (corners) of the trapezium.
It could be a trapezium, a kite or an arrowhead.
its..trapezium
It can be a trapezium, kite, arrowhead, or a general quadrangle. Squares and rectangles also have one right angle - they have more that 1, but that still means they have 1.
A trapezium, a kite, a number of miscellaneous quadrilaterals.
No, a triangle cannot have more than one obtuseangle.
It could be a kite, a trapezium, a chevron or just an irregular quadrilateral with one right angle and no specific name.
the answer is 27' * * * * * Yet another totally nonsensical answer by "The Community"! An angle on a trapezium can have any value between 0 and 180 degrees and the only additional requirement is that one of its adjacent angles is supplementary and that the other adjacent angle is not supplementary - these conditions ensure that there is only one pair of parallel sides..
It could be an isosceles triangle that is not right angles; an isosceles trapezium, a trapezium where one of the parallel sides is equal to one of the sloped sides; any irregular polygon with 5 or more sides where two are equal, and no right angles.
