Hello everyone. 
Is this question correct to ask about angles?
What do we call the angle that is smaller than the right angle?
What do we call the angle that is bigger than the right angle?
What is the value of this angle?
(Is it correct to use smaller or bigger to describe angles?)

Answer

An angle that's smaller than a right angle is acute. One that's larger is obtuse.

I hope that helps!

If you are asking a question about 'angles' in general, I would say:

"What do you call AN angle that is bigger/ smaller than A right angle?"
