<p>Parallel lines are a fundamental concept in geometry, exhibiting several distinctive properties that simplify geometric problems involving parallel lines. The properties of parallel lines include: they never intersect, they are always equidistant from each other, and corresponding angles formed by a transversal are equal. These properties assist students in analyzing and solving problems related to angles, slopes, and transversal lines. Now let us learn more about the properties of parallel lines.</p>
