of the angle.

In these lessons, we will learn the following types of angles:

right angles, acute angles, obtuse angles, straight angles, reflex angles and full angles.

A **right angle** is an angle measuring **90** degrees. Two
lines or line segments that
meet at a right angle are said to be perpendicular.

The following video explains more about right angles.

An **acute angle** is an angle measuring between **0** and
**90** degrees.

An **obtuse angle** is an angle measuring between **90**
and **180** degrees.

A **straight angle**
is a straight line and it measures **180** degrees.

What are the differences between a right, acute, obtuse and straight angle?

A reflex angle is an angle measuring between **180** and **360** degrees.

A full angle is an angle of one complete turn which is 360 degrees.

Anangle of one whole turnis 360˚.
