Of the regular polygons, only two quadrilateral shapes have all right angles:the rectangle and the square (all sides equal).These are types of parallelograms (4 right angles, 2 sets of parallel opposite sides).
A square or rectangle are the only regular polygons, but many other shapes have two right angles and two parallel lines.
Interior angles total ((2 x 7) - 4) right angles which is 900 degrees. Exterior angles total 360 degrees. This is true of all convex polygons.
There is no quadrilateral that meets these requirements. It is, of course, possible for a pentagon (or polygons with 6 or more sides) to have 4 equal sides and only 2 right angles.

In math when 2 polygons have the same angles, lines and size, they would be congruent.

Quadrilaterals are polygons having four sides. Quadrilaterals may have 1, 2, or 4 right angles. It is impossible for a quadrilateral to have exactly 3 right angles because the fourth angle would also be a right angle.
There is no quadrilateral that meets these requirements. It is, of course, possible for a pentagon (or polygons with 6 or more sides) to have 4 equal sides and only 2 right angles.

trapezoid
Nothing, it's impossible.* * * * *Only if you limit yourself to quadrilaterals. But why? It is, of course, possible for a pentagon (or polygons with 6 or more sides) to have 4 equal sides and only 2 right angles.
irregular polygons are just polygons that do not have equal angles and side so a scaling and isosceles triangles are 2 and trapezoid is another.
A circle, it has no angles.There are a infinite number of 2-d shapes that have no right angles.TrapeziumRhombusAll polygons except a square or a rectangleAll triangles except a right angle triangleAny irregular shapeetc.etc.
