5.
We know that,
An angle which is smaller than a right angle is called an acute angle.
An angle with measure 90° is called a right angle.
An angle which is greater than a right angle but smaller than a straight angle is called an obtuse angle.
An angle with measure 180° is called a straight angle.
An angle which is greater than a straight angle but smaller than a complete angle is called a reflex angle.
Now, from these results
(a) Given angle is smaller than a right angle, so it is an acute angle.
(b) Given angle is more than a right angle, so it is an obtuse angle.
(c) Given angle is a right angle.
(d) Given angle is more than a straight angle, so it is a reflex angle.
(e) Given angle is a straight angle.
(f) Both angles are smaller than a right angle, so both these are acute angles.
