Angles and types of Angles

Today lets talk about Angles..

First of all lets understand what is an Angle is..............

An angle is an outline formed by two influence with the similar opening point.
The point at which the arms meet (o) is known as the vertex of the Angle.

Types of Angles:

Lets go through the different types of angles.

Right Angle: An angle whose measure is 90 degrees is called as a Right Angle.

Acute Angle: An angle whose measure is less then one right angle (i.e., less than 90 degrees). Is called an Acute Angle.

Obtuse Angle: An angle whose measure is more than one right angle and less than two right angles (i.e., less than 180 degrees and more than 90 degrees ) is called an Obtuse Angle.

Straight Angle: An angle whose measure is 180 degrees is called a Straight Angle.

Reflex Angle: An angle whose measure is more than 180 degrees and less than 360 degrees is called a Reflex Angle.


Complete Angle: An angle whose measure is 360 degrees is called a Complete Angle.
