Two angles with a common vertex and two opposite extension lines are called antipodal angles. The intersection of two straight lines will produce an intersection point, and taking this intersection point as the vertex will produce four angles. We call two nonadjacent angles opposite to each other, or one of them is opposite to the other.
In geometry, antipodal angle is the positional relationship between two angles. The nature of antipodal angle is that if two angles are antipodal angles, then the two angles are equal. On the same plane, two opposite angles are equal.
Corner features:
1 has a common vertex.
2. Have the advantage of men.
3. The other side of the two corners is the opposite extension line.
4. Adjacent complementary angles appear in pairs, which are mutually adjacent complementary angles.
5. Two adjacent corners make a right angle.
6. Two adjacent complementary angles are complementary, that is, they add up to 180 degrees.

Adjacent complementary angle
Adjacent complementary angles include two requirements: positional relationship and quantitative relationship between two angles. If two angles are adjacent complementary angles, their sum is equal to 180, and the bisectors of two tangent angles are perpendicular to each other. Identifying whether two angles are adjacent complementary angles can start from the following aspects:
1 has a common vertex.
2. Have the advantage of men.
3. The other side of the two corners is the opposite extension line.
4. Adjacent complementary angles appear in pairs, which are mutually adjacent complementary angles.
5. Two adjacent corners make a right angle.
6. Two adjacent complementary angles are complementary, that is, they add up to 180 degrees.
