When two parallel lines are cut by a transversal, the two pairs of angles on opposite sides of the transversal and outside the parallel lines, and the angles in each pair are congruent.
It is the alternate angle to the angle of elevation
If angle 12 is located on a transversal intersecting two parallel lines, then the alternate exterior angles would be the angles formed on the opposite sides of the transversal and outside the two lines. For instance, if angle 12 is positioned at the top left, then angle A, located at the bottom right outside the parallel lines, and angle B, located at the top right outside the parallel lines, would both be alternate exterior angles with angle 12.

If you mean a regular pentagon then each interior angle is 108 degrees and each exterior angle is 72 degrees
If you mean exterior angle is twice its interior angle then an equilateral triangle will fit the given description because each interior angle is 60 degrees and each exterior angle is 120 degrees
Both alternate interior and alternate exterior angle pairs lie on opposite sides of the transversal.
Pairs of Alternate Exterior Angle are Congruent

The answer depends totally on how the angles are numbered. And since you have not bothered to provide that information, I cannot provide a sensible answer.

1. Alternate Interior Angles 2. Alternate Exterior Angles 3. Corresponding Angles 4. Same-Side Interior Angles 5. Same-Side Exterior Angles
If you mean exterior angle is twice its interior angle then an equilateral triangle will fit the given description because each interior angle is 60 degrees and each exterior angle is 120 degrees
