4, making it a rectangle or a square. If you don't want either of those, then 2.
Can't have 3 because interior angles total 360o.

An irregular four-sided shape, or quadrilateral, can have anywhere from zero to four right angles. The specific number of right angles depends on the individual angles of the shape; for example, a rectangle has four right angles, while a trapezoid may have none. Thus, the count of right angles in an irregular quadrilateral can vary widely.

No because a quadrilateral has 4 sides but doesn't have to have right angles. For example the. Trapezoid doesn't,t have right angles but it is a quadrilateral
Just the one and the other two angles must then be acute angles
All quadrilateral have four angles. It is possible that all four angles are right angles, even if the quadrilateral is not a square (this would be a rectangle).
If it is a quadrilateral it cannot be "not a quadrilateral"!
A quadrilateral having four right angles is called a rectangle.
A quadrilateral is any shape with four sides; angles can be acute or obtuse. A perfect square is the only quadrilateral with only right angles.

A Rectangle or a square. The word 'rectangle' comes from Latin and means 'Right(Recto) Angles'.
It's impossible for a quadrilateral to have no equal sides and have right angles.
An irregular four-sided shape, or quadrilateral, can have anywhere from zero to four right angles. The specific number of right angles depends on the individual angles of the shape; for example, a rectangle has four right angles, while a trapezoid may have none. Thus, the count of right angles in an irregular quadrilateral can vary widely.
The sum of the interior angles of a quadrilateral is 360 degrees. If three of the angles are right angles, that is, of 90 degrees each, the the fourth must be 90 degrees. So you can have a quadrilateral with three right angles but its fourth angle will also be a right angle. So exactly 3 right angles is not possible.
No, if it has right angles it is a special case, such as rectangle, but in general it does not have to have any right angles
