When a transversal crosses two lines, eight angles are created. Corresponding angles are the ones that lie on the same side of the transversal and in the same relative position at each intersection. For example, the angle at the top-left corner of the first intersection aligns with the angle at the top-left corner of the second intersection. The important property is that these angles are equal when the two lines are parallel, which is why this definition is used. The other descriptions refer to different angle relationships or concepts (such as alternate interior/exterior angles or angles formed by chords in circles) and don’t capture the idea of corresponding angles.
