The answer is 2 acute angles and 2 obtuse angles.

An acute angle is an angle that is smaller than 90 degrees.
an obtuse angle is an angle that is larger than 90 degrees.

There are no right angles in the figure shown above. 
2 acute angles (the two on the top because they are less than 90 degrees) and 2 obtuse angles (the two on the bottom because they are more than 90 degrees). There are no right angles.
