A right angle always adds up to 90 degrees. So all 90 degree angles are right angles. You can always tell that angles are right angles if they have a little square between the arms of the angle.

Anything less than (smaller) a 90 degree angle is called an acute angle.

If the angle is larger (bigger) than a 90 degree angle, then the angle is called an obtuse angle.

If the angle is a lot larger (bigger) than a 90 degree angle, then the angle is called an reflex angle.

In Maths, we use a protractor to help us draw angles. Notice how a protractor has 2 sets of numbers (inside and outside). This is where you have to think in order to determine which set of numbers you are going to use.
