In geometry, angles can be classified according to the size 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.
The following table shows the different types of angles: right angles, acute angles, obtuse angles, straight angles, reflex angles and full angles. Scroll down the page if you need more explanations about each type of angles, videos and worksheets.
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.
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.
An angle of one whole turn is 360°.
