What is the difference between, acute, obtuse, right, straight and reflex angles?

• Right angle is between 180 and 360 degrees
• The difference lies in the measurement of the angles. Acute angle is less than 90 degrees, obtuse angle is between 90 and 180 degrees, right angle is exactly 90 degrees, straight angle is exactly 180 degrees, and reflex angle is between 180 and 360 degrees.
• Obtuse angle is less than 90 degrees
• Acute angle is between 90 and 180 degrees
