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.
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°.
