There is no deep meaning to it.
They are lines that cut through parallel lines
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.
Corresponding angles are congruent means that when two parallel lines are intersected by a transversal, the pairs of angles that occupy the same relative position at each intersection are equal in measure. For example, if a transversal crosses two parallel lines, the angle in the upper left position at one intersection is equal to the angle in the upper left position at the other intersection. This property is fundamental in geometry and is used to establish relationships between angles in various geometric proofs and problems.
Usually this is about parallel lins and transversals. Imagine 2 horizontal lines which are parallel. Now imagine a transverse line from uper left to lower right crossing thru the two parallel lines. This makes 8 angles. The top line and the transversal create an angle on the upper right. So does the lower line and the transversal. These are on the same side of the transrevsal.
There are at least 28 different pairs of angles: 66 if the first two lines are not parallel. Your question needs to be more specific as to which angles you mean.

There are three lines in the figure described. Two of the lines never meet, these are the parallel lines. The third line crosses the other lines, it is the "transversal" line. If the parallel lines are really line SEGMENTS then each can be bisected (cut into two equal lengths) This is what your description states.
When a transversal line cuts through parallel lines it creates equal alternate angles.
Corresponding angles are congruent means that when two parallel lines are intersected by a transversal, the pairs of angles that occupy the same relative position at each intersection are equal in measure.

Alternate int angles are two interior angles which lie on different parallel lines and on opposite sides of a transversal

When two lines are crossed by another line (called the Transversal)
When a transversal line cuts through parallel lines corresponding angles are formed and they are equal in sizes Alternate angles are also formed and they too are equal in size
Corresponding congruent angles refer to pairs of angles that are in the same relative position at each intersection where a straight line crosses two parallel lines. When the lines are cut by a transversal, the angles that occupy the same position at each intersection are considered corresponding angles. If these angles are congruent, it means they have equal measures, confirming the parallel nature of the lines. This concept is often used in geometry to prove the properties of parallel lines.
