no, a square consists of all right angles
Yes.
Yes. Every triangle with an obtuse angle must have two acute angles.
Yes providing that the other 2 angles are acute

Yes, it is possible to draw a reflex angle such that the other angle formed by the arms is obtuse. A reflex angle is an angle that measures more than 180 degrees but less than 360 degrees, while an obtuse angle measures more than 90 degrees but less than 180 degrees. When you have a reflex angle, the remaining angle (the one that complements it to a full circle) can easily be obtuse. For instance, if the reflex angle is 210 degrees, the other angle would be 150 degrees, which is obtuse.

yes. if the reflex angle is 260 degrees, the other is 100 which is obtuse
Acute or obtuse: Yes. Straight: No.

No - simply because a 'reflex' angle (I think that's what you meant) is more than 180 degrees, and an obtuse angle is between 90 and 180 degrees.

Yes, it is possible to draw a quadrilateral with a reflex angle and an obtuse angle. A reflex angle measures more than 180 degrees, while an obtuse angle measures between 90 and 180 degrees. To create a quadrilateral with these angles, you can draw a shape with one reflex angle (greater than 180 degrees) and one obtuse angle (between 90 and 180 degrees), along with two acute angles (less than 90 degrees).
