Different Types And Kinds of an Angle in Geometry

 

Different types and kinds of an Angle

Here are various types of an angle which are classified in Geometry. 

 [1. Acute Angle] 

 Definition!

An angle less than 90 degrees are called Acute Angle.

Example: 40°, 35°,50° etc. 

[2. Right Angle] 

Definition!

An angle exactly equal to 90 degrees is called Right Angle.

Example: (90°)

 [3. Obtuse Angle] 

 Definition!

An angle greater than 90 degrees but less than 180 degrees is called Obtuse Angle. 

Example: 127°, 167°,170°,etc

[4. Straight Angle]

Definition! 

An angle that measures exactly 180° is called Straight Angle.

Example : (180°)

 [5. Reflex Angle] 

 Definition!

An angle which is greater than 180 degrees but less than 360 degrees is called Reflex Angle. 

Example: 220°, 330°,335° etc

[6. Full Angle OR Complete Angle] 

Definition!

An angle which is equal to 360 degrees is called Complete Angle.

Example: (360°)

[7. Zero Angle]

Definition! An angle which is equal to 0 degrees is called Zero Angle. 

Example: (0°)

Other Kinds of Angles:

1. [Complementary Angles]

Two angles whose sum is 90 degrees.

2. [Supplementary Angles]

Two angles whose sum is 180 degrees.

3. [Adjacent Angles]

Two angles whose vertex is common.

4. [Opposite Angles]

Those Angles which are formed by two intersecting lines, which are opposite to each other and are equal is called opposite Angles.
