- 2. presented by , J.Merlin Raja Beryl, Department of Mathematics . Types of Angles
- 3. Angle If two rayshave an common end point they form an angle . The two rays forming an angle are called the arms of the angle . The common end point is called a vertex of the angle .
- 4. Types of angles Dependingon the position of the arms ,there are different types of angles . Let's learn about them...
- 5. Types of Angles Thereare 6 Types of angles: Acute angle. Right angle. Obtuse angle. Straight angle. Reflex angle. Complete angle.
- 6. Acute angle An anglewhose measure is more than 0° but less 90° is called an acute angle . Example : 30°, 45°,etc

- 11. Obtuse angle An anglewhose measure is greater than 90°and less than 180° is called an obtuse angle . Example :100°,160°, etc
- 12. Other examples forobtuse angle:
- 13. Straight angle An anglewhose measure is 180° is called a straight angle. Example :180°
