A straight angle is an angle that measures exactly 180°
A reflex angle is an angle that measures more than 180°, but measures less than 360°.
Edit: I really like that answer that the controbuter did above ^. I just wanted to add something. A straight angle is an angle that is straight. A reflex angle would be an angle larger than a straight angle. It's an angle that's in the opposite side of a right angle or an acute.
A reflex angle
It is an obtuse angle
An angle at 181 degrees would be considered a "Reflex" angle. This is because it exceeds 180 degrees which is a "Straight" angle.
reflex angle
An angle that measures 185 degrees would be considered a "reflex" angle. This is because anything above 180 (straight) is considered "reflex". Anything between 90 and 179 is "obtuse" and anything below 90 is "acute".
A reflex angle.
No, 180 degrees is a straight angle. A reflex angle is one whose value is between 180 and 360 degrees.
Straight angle
Obtuse, straight, reflex.
Oh, dude, a reflex angle is greater than 180 degrees, so if you draw one arm of the angle straight, the other arm would have to be pointing backwards, which is like, not really a thing in normal geometry. So, technically, no, you can't have a straight angle and a reflex angle sharing an arm. But hey, if you're feeling creative, go for it, who am I to stop you?

They can make an obtuse angle, a straight angle or a reflex angle.
yes
A straight angle is pi radians (180 degrees). A reflex angle is more than pi radian but less than 2*pi radians (between 180 and 360 degrees).
If by "then" you meant "than", then the answer could be a straight angle.
