I dont know thats why im trying to ask you guys!
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
Yes, a trapezium (or trapezoid in American English) can have one right angle. In such a trapezium, one pair of opposite sides is parallel, and the right angle can occur between one of the non-parallel sides and one of the parallel sides. This configuration is common in various geometric applications and can have unique properties based on the angles and lengths of the sides.
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.
Apparently, yes. It has 2.
