Angle comparison and operation is an important knowledge point in mathematics, which mainly includes angle comparison, angle sum and difference operation and angle multiplication operation. The following are some contents about angle comparison and operation of Onion College:

1. Comparison of angles: The comparison of angles is judged according to their degrees. The angle with a large degree is large, and the angle with a small degree is small. Angles with the same degree have the same size.

2. Sum and difference operation of angles: Sum and difference operation of angles refers to the addition or subtraction of degrees of two angles. According to the degree of angle, a new degree of angle is obtained. For example, if the degree of angle A is 30 and the degree of angle B is 50, then the degree of angle C is 80.

3. Angle multiplication: Angle multiplication refers to multiplying an angle degree by an integer to get a new angle degree. For example, if the degree of angle A is 30 degrees, then the degree of angle B, which is twice that of angle A, is 60 degrees.

4. Complementary angle and complementary angle: Complementary angle means that the sum of degrees of two angles is 90, and they are complementary angles. Complementary angle means that the sum of degrees of two angles is 180, and they are complementary angles.
