Let a be the angle. 1. Zero: a = 0 (angle is equal to zero degrees) 2. Acute: 0 < a < 90 (the angle is between 0 and 90 degrees) 3. Right: a = 90 (the angle is 90 degrees) 4. Obtuse: 90< a < 180 (The angle is between 90 and 180 degrees) 5. Straight: a = 180 (the angle is a straight line it is equal to 180 degrees) 6. Reflex: 180 < a < 360 ( the angle is between 180 and 360 degrees) 7. Full (revolution): a = 360 (The angle is equal to 360 degrees a full circle.)
