Remote interior angles are the angles that are not adjacent to a given exterior angle but are inside the triangle. For each exterior angle of a triangle, there are two remote interior angles. The sum of these remote interior angles is equal to the measure of the exterior angle. Thus, if you have a specific exterior angle, you can identify the two corresponding remote interior angles.

Are two angle of a triangle that are not adjacent to the exterior angle
Yes, it is.
In triangle ADE, if angle GEA is an exterior angle, the remote interior angles are angles DAE and DEA. These are the angles inside the triangle that are not adjacent to the exterior angle GEA. According to the Exterior Angle Theorem, the measure of angle GEA is equal to the sum of the measures of angles DAE and DEA.
In a triangle, the remote exterior angle is formed by extending one side of the triangle, while the opposite interior angles are those that do not share a vertex with the exterior angle. According to the exterior angle theorem, the measure of the remote exterior angle is equal to the sum of the measures of the two opposite interior angles. This relationship holds because the angles in a triangle sum up to 180 degrees, and the exterior angle effectively "completes" the linear pair with the adjacent interior angle, reinforcing the equality. Thus, the theorem demonstrates a fundamental property of triangles and their angles.
