What is intersecting lines?

Intersecting lines are two or more lines that cross or meet at a common point. This point where the lines intersect is called the point of intersection. When two lines intersect, they form angles at the point of intersection. The angles formed can be classified as vertical angles, adjacent angles, supplementary angles, complementary angles, or linear pairs.

Intersecting lines can have different orientations, such as perpendicular lines, which intersect at a 90-degree angle, or oblique lines, which intersect at any other angle. When two lines intersect, they create four different angles: two pairs of vertical angles that are congruent, two pairs of adjacent angles that are supplementary, and two pairs of linear pairs that are supplementary.

Intersecting lines are commonly found in geometry and can be used to solve problems related to angles, shapes, and transformations. They are fundamental in understanding geometric concepts and properties, such as parallel lines, transversals, and the angles formed by intersecting lines.
