Yes. Every triangle with an obtuse angle must have two acute angles.
no, a square consists of all right angles

yes. if the reflex angle is 260 degrees, the other is 100 which is obtuse
no, a square consists of all right angles
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 providing that the other two angles are acute
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).
Yes providing the other 2 angles are acute
One angle must be an obtuse angle and the other two angles must be acute angles
