its a square because squares have 4 sides and one pair of parellel sides and more then one right angle.if you don't believe me i happen o be in 3 grade in a advance class witch means more work for us and work from other grades like 8 grade work. Square have 2parallel sides not one.
Edit this is true to an extent except the answer could also be a rectangle. But if you are looking for a four sided figure with a single right angle the answer would be a kite.
Sorry, you either have more than one right angle or more than four 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.
You can have two right angles and still be only a trapezoid. With three right angles then it would be a rectangle.
A kite could fit the given description.
A right hendecagon can have no parallel sides because there are eleven sides to a hendecagon. It is not a requirement that there be any pairs of parallel sides in an irregular hendecagon, although there could be one or more pairs.

There is no such thing as an angle with parallel sides. The question needed proof-reading. It's too late now.

Yes
Any polygon with 4 or more sides can always have a right angle.

A polygon with 4 or more sides can have more than one right angle.

That depends somewhat on other characteristics of the polygon.-- If it has four sides and one pair of them is parallel and congruent, then theother pair must also be parallel and congruent, and it's called a parallelogram.-- If it has four sides, parallel and congruent opposite sides, and a right angle,then it's called a rectangle.-- If it has four sides and all four sides are congruent, then opposite sides must beparallel, and it's called a rhombus.-- If it has four sides and both pairs of sides are parallel and all four are congruentand it has a right angle, then it's called a square as well as a rhombus.-- Any polygon with more than four sides can have at least one pair of oppositeparallel congruent sides and possibly more, but doesn't necessarily have.-- If it's a regular polygon, then it has one or more such pairs of sides if, and only if,it has an even number of sides.-- In any case with more than four sides, the polygon is named for its number of sides.And I believe that pretty well covers it.
I don't think there's a special name for that.
A four-sided shape with one right angle is a quadrilateral. There is no more specific term, unless it has more than one right angle or has equal sides.
