It could be a kite, an arrowhead or an irregular quadrilateral with a right angle - which has no specific name.
The only diagonal line in a right-angle triangle is the hypotenuse. So the answer is 1.
There are lots of polygons like that. If by 1 right angle, you mean exactly 1 right angle, there are no such quadrilaterals, but there are pentagons (in fact n-gons for all n>=5.)
That depends on what type of shape it is as for example a triangle can only have 1 right angle of 90 degrees.
sin of angle a = opposite/hypotenuse = 1/3 sin-1(1/3) = 19.47122063 degrees
a kite
A kite An irregular quadrilateral can be made having only 1 right angle.
Quadrilateral. No other special name. A kite could have 1 right angle - that's possible, but there is no special name for a quadrilateral with only 1 right angle.
Two possibilities are a kite, or an irregular quadrilateral with one right angle!
It could be a kite, an arrowhead or an irregular quadrilateral with a right angle - which has no specific name.
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.
It ha one right angle, two obtuse angles and one acute angle
1. A triangle is a right triangle if and only if it has a right angle. 2. A triangle has a right angle if and only if it is a right triangle.
A rectangle has only 1 right angle.

Yes, only 1.
