Mastering Pairs of Straight Lines

A pair of straight lines is a set of two lines that do not intersect each other and are not parallel to each other.

Some properties of a pair of straight lines include: they can be perpendicular to each other, they can be equal in length, and they can be at an angle to each other.

A pair of straight lines can be represented mathematically using the general equation of a straight line, which is Ax + By + C = 0, where A, B, and C are constants.
