There are a couple of geometric angles we should know about. We start with the right angle which is the 90 degrees angle. Then we have the acute, which is less than 90 degrees. We have the obtuse angle, which is more than 90 degrees. There is the straight angle which is exactly 180 degrees. A reflex angle is between 90 and 180 degrees. Lastly. there is the full angle which is the full 360 degrees.
