2. Any angle that measures greater than 0° and less than 90° is called an acute angle.  Acute angles measure less than 90° Therefore, 67°, 45°, 23°, 52°, 86°, 14° are all examples of acute angles .

3. If we slice a pizza into 5 or more slices, each slice of pizza will make an acute angle. The arms of a wall clock make acute angles at several hours of the day.  For example, 10 o’clock.

4. An obtuse angle is a type of angle that is always larger than 90° but less than 180°. In other words, it lies between 90° and 180°.  In the given figure, ∠XYZ shows an obtuse angle.

5. The angle formed by the screen of an open laptop Recliners are commonly seen in movie theatres, homes, and other places have a special feature of the backrest of it going back to help you relax and unwind .

6. Any angle whose measure is equal to 90° is a right angle. In the given figure, ∠ AOB shows a right angle .

7. Sailing boats frequently have sails in the right triangle design . The sails help to maneuver the boats easily through action and reaction. A ladder inclined to the wall makes a triangle with ground and wall. The angle between the ground and the wall is a right angle. The ladder is the hypotenuse of this right-angled structure

8. In geometry, a straight angle is defined as an angle that is equal to 180 degrees. The reason it is called a straight angle is because it appears as a straight line . 

9. Wall clock is the best example of a straight angle. For example, 6 o’clock. If we see a pencil, then we will see it will make a straight angle example.

10. A complete angle is defined as an angle that measures exactly 360°. It thus indicates a complete turn or rotation around a point . Also known as ‘full angle’ it is represented using the symbol 2π (where π is a pie).

11. An angle made by the Bangle at the centre measures a complete angle . An angle made by the coin measures a complete angle.
