Parallel Lines Definition and Geometry Illustration #3858336 (License: Personal Use)

The image displays a geometric diagram where lines L and M are shown as arrows on plane P, labeled with the parallel symbol (∥). Below the figure, the precise definition is given: “Two lines are parallel if they are coplanar and don’t intersect.” This visual reinforces foundational Euclidean geometry principles taught in middle to high school mathematics.

Used in educational web pages, math tutorials, or geometry lesson modules to introduce or review the concept of parallel lines; matches user intent for learning definitions, visualizing spatial relationships, or preparing for standardized tests.
