Interior Angles of a Triangle
Exterior Angles of a Triangle

In the following diagram you can see exterior angles and interior angles.

Adjacent Interior Angles are shown with diagram in following:

In the below diagram you can see that ∠ 2 is an exterior angle.
So, ∠ 3 is Adjacent Interior Angle to ∠ 2

In the below diagram you can see that ∠ 6 is an exterior angle.
So, ∠ 5 is Adjacent Interior Angle to ∠ 6

In the below diagram you can see that ∠ 1 is an exterior angle.
So, ∠ 1 is Adjacent Interior Angle to ∠ 4
