supplementary
If two parallel lines are cut by a transversal, the sum of the measures of the interior angles on the same side of the transversal is 180 degrees. This is due to the properties of parallel lines and the angles formed by the transversal, which create corresponding and consecutive interior angles. Hence, these angles are supplementary.
When non-parallel lines are cut by a transversal, alternate interior angles are not necessarily equal. Instead, the relationship between these angles depends on the specific measures of the angles formed by the transversal and the non-parallel lines. Therefore, unlike the case with parallel lines, alternate interior angles do not have a consistent property of being congruent when the lines are not parallel.

Parallel lines cut by a transversal form congruent alternate interior angles.
Alternate interior angles are equal on a transversal that passes through parallel lines.

When 2 parallel lines are cut by a transversal some of the pairs of angles which are formed are called alternate angles whereas other pairs are called interior angles.

When two parallel lines are cut by a transversal, several relationships among the interior angles can be observed. The interior angles on the same side of the transversal are supplementary, meaning they add up to 180 degrees. Additionally, the interior angles formed on opposite sides of the transversal but within the parallel lines are equal. This leads to the conclusion that angles formed in this configuration exhibit specific congruence and supplementary properties.
Only if the lines cut by the transversal are parallel.
Remote interior angles and remote exterior angles.
Angles on opposite sides of the transversal and between the parallel lines
Alternate interior angles are formed when a transversal intersects two parallel lines. For example, if line A and line B are parallel, and line C is the transversal, then the angles that are on opposite sides of line C and inside the parallel lines (e.g., angle 3 and angle 5) are alternate interior angles. Another example could be angles 4 and 6, which are also on opposite sides of the transversal and between the two parallel lines.
