Here are the examples of the different angles that exist:
1) An acute angle is an angle that is more than 0° and is less than 90°.
2) A right angle is an angle that is exactly equal to 90°
3) A obtuse angle is an angle that is more than 90 degrees but less than 180°.
4) A straight angle is an angle that is exactly equal to 180°. It forms a straight line.
5) A reflex angle is an angle that is more than 180° but is less than 360°
6) A Full angle is an angle that measures 360°. It makes a circle.
Here are the answers to your specific question - Question 2, exercise 5.3 of Class 6 - Math - Understanding Elementary Shapes Page 95:
a) Acute angle - it less than 90° and more than 0°
b) An obtuse angle - it measures more than 90° but less than 180°
c) Right angle - measures 90°
d) A reflex angle - measures more than 180° but less than 360°
e) Is a straight angle - it measures 180°
f) The 2 angles are acute angles - they are less than 90° but more than 0°

Types of angles
1. Right angle: An angle whose measure is 90° called a right angle
2. Straight angle: an angle whose measure is 180° is called a straight angle.
A straight angle has two right angles.
3. Reflex angle:
An angle whose measure is greater than 180° and less than 360° is called reflex angle.
4. Complete angle:
An angle whose measure is 360° called a complete angle.
5. Acute angle:
An Angle whose measure is less than 90° is called an acute angle.
6. Obtuse angle:
An angle whose measure is greater than 90° and less than 180° is called an obtuse angle.
