Take a look at the examples of consecutive angles seen earlier and verify that:

The angles AOC and COL have no common internal points.

Angles AÔC and AÔB have common internal points.

The angles COB and AON have common internal points

Verify that the angles AOC and COB are consecutive and do not have common internal points. That's why they are called **adjacent angles. **

Like this:

Two angles are**adjacent**when they are consecutive and do not have common internal points.

Note:

Two competing lines determine several adjacent angles. Examples:
