TYPE OF ANGLES
- 2. presented by , J. Merlin Raja Beryl, Department of Mathematics . Types of Angles
- 3. Angle If two rays have 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 Depending on the position of the arms ,there are different types of angles . Let's learn about them...
- 5. Types of Angles There are 6 Types of angles: Acute angle. Right angle. Obtuse angle. Straight angle. Reflex angle. Complete angle.
- 6. Acute angle An angle whose measure is more than 0° but less 90° is called an acute angle . Example : 30°, 45°,etc
- 8. Examples for acute angleExamples for acute angle
- 9. Right angle An angle whose measure is 90° is called a right angle . Example :90°
- 10. Other examples for right angle
- 11. Obtuse angle An angle whose measure is greater than 90°and less than 180° is called an obtuse angle . Example :100°,160°, etc
- 12. Other examples for obtuse angle:
- 13. Straight angle An angle whose measure is 180° is called a straight angle. Example :180°
- 15. Reflex angle An angle whose measure is greater than 180° and less than 360° is called reflex angle . Example :230°, 320°
- 17. Complete angle When the arms take the complete turn then the angle of measure 360° is formed . This type of angle is called a complete angle .
