Angle

An angle is formed when two lines or line segments intersect each other. In our everyday life, we see different types of Angles formed between the edges of plane surfaces. We see different Types of Angles such as Acute Angle, Right Angle, Obtuse Angle, Straight Angle, Reflex Angle, and Full Rotation Angle.

Different Types of Angles

We will discuss types of angles and their properties :-

Acute Angle

An angle that is more than 0° and less than 90° is called Acute Angle. Examples of acute angles are 10°, 60°, 70°, and 55°. You can observe the following ∠ABC which is an acute angle.

Acute Angle

Straight Angle

An angle that is exactly 180° is called a Straight Angle. Observe the following figure which is a straight angle.

Straight Angle

Right Angle

An angle that is exactly 90° is called a Right Angle.

Right Angle

Obtuse Angle

An angle that is more than 90° and less than 180° is called Obtuse Angle. Examples of obtuse angles are 95°, 100°, 120°, and 140°. You can observe the following image.

Obtuse Angle

Reflex Angle

An angle that is more than 180° and less than 360° is called Reflex Angle. Examples of reflex angles are 190°, 220°, 240°, and 250°. You can observe the following image.

Reflex Angle

Full Rotation Angle

An Angle that is exactly 360° is called a Full Rotation Angle.

Full Rotation Angle
