An angle is two rays that share the same endpoint form an angle.

Acute Angle :

Is an angle that is less then 90 degrees .

Right Angle :

A right angle is an internal angle which is equal to 90 degrees. The right angle has a special symbol and that's an easier way to find out if it is a right angle.

Obtuse angle :

A obtuse angle is angle that is more than 90 degrees but less than 180 degrees.

Straight angle (also called Flat angle) :

A straight angle is 180 degrees and it changes the direction the opposite way.

Reflex angle :

A reflex angle is more than 180 degrees and less than 360 degrees
