Answer 3

Definition of Parallel Lines

Two lines on a plane are considered parallel if they do not intersect.

This is a fundamental concept in geometry and has important applications in various fields such as mathematics, engineering, and physics.

Additional Information

Parallel lines have the same slope, and they will never intersect, no matter how far they are extended. In the context of Euclidean geometry, parallel lines are assumed to be in the same plane.

In terms of angles, when a transversal intersects two parallel lines, corresponding angles are congruent, alternate interior angles are congruent, and alternate exterior angles are congruent.

The concept of parallel lines is crucial in understanding the properties of shapes and figures, as well as in solving various mathematical problems and real-world applications.
