Answer:
The correct options are C and D.
Step-by-step explanation:
The remote interior angles are same as opposite interior angle.
In a triangle the remote angles of an exterior angle are the opposite interior angles of the exterior angle. For each exterior angle we have two remote angles.
Angle 1 is the exterior angle so its has two opposite interior angles.
Angle 3 and 4 are opposite interior angles of angle 1, therefore we can say that the angle 3 and 4 are remote interior angles of 1.
Options C and D are correct.
