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.
If ONLY two right angles, then it could be a right angled trapezium or a kite If more than two it must be a rectangle (a square is an equilateral rectangle).
If only right angles, then the answer is squares and rectangles. If one or more right angles, the answer will include trapezium, kite and any (irregular) polygon with 5 or more sides. A single triangle can have only one right angle, but several triangles can have right angles, (sorry, that's purely a linguistic argument).
I think the answer is SQUARE * * * * * A correct but incomplete answer. If ONLY two right angles, then it could be a right angled trapezium or a kite If more than two it must be a rectangle (a square is an equilateral rectangle).
The most right angles a triangle can possibly have is 1. Any more than that, and it has to be a quadrilateral.
A parallelogram, a rhombus, kites, arrowheads, trapezium and irregular quadrilaterals. However, some kites, arrowheads, trapezium and irregular quadrilaterals can have one (or more) right angles.

A general trapezium, and selected versions of polygons with 5 or more sides.
A right angled triangle, A square, rectangle, a right trapezium, Selected versions of irregular polygons with 5 or more sides.
No REGULAR polygon can have three right angles in it. Any polygon with five or more sides CAN have three right angles, as long as it's not regular.

If it had two right angles it would have more then three sides
A trapezoid cannot have three right angles. If it did it would either need more than four sides, or it would be a rectangle or a square.

Acute triangles. They can have three angles, all less than 90 degrees (total is 180 degrees).Shapes with more than three sides must have angles of 90 degrees or more because the total of their angles must be 360 degrees (quadrilaterals) or more.
