Ancient mathematicians introduced the concept of lines to represent straight objects which had negligible width and depth. Considered as a breadth less length by Euclid, lines form the basis of Euclidean geometry.
Two lines are parallel if the have the same slope. Now let's look at some examples that use these ideas to find lines that are either parallel or perpendicular to a given line passing through a specific point. Parallel structure, or parallelism, means using the same pattern of words to show that two or more words or ideas are of equal importance.
