Is a line parallel to itself?
In geometry, parallel lines can be defined as two lines in the same plane that are at equal distance from each other and never meet. They can be both horizontal and vertical. We can see parallel lines examples in our daily life like a zebra crossing, the lines of notebooks, and on railway tracks around us.
Lines are parallel if they are always the same distance apart (called "equidistant"), and will never meet. Just remember: Always the same distance apart and never touching. The red line is parallel to the blue line in each of these examples: Parallel lines also point in the same direction. Parallel lines have so much in common.
Parallel lines are lines in a plane which do not intersect. Like adjacent lanes on a straight highway, two parallel lines face in the same direction, continuing on and on and never meeting each other. In the figure in the first section below, the two lines ...
Parallel lines are lines that never intersect because they are always the same distance apart. For example, Parallel lines are seen in many common 2D shapes. For example, Each side of a square is made of a line segment that is part of a line. The opposite sides of a square are parallel. There are also many examples of parallel lines in real life.
Parallel lines are lines that never intersect, and they form the same angle when they cross another line. Perpendicular lines intersect at a 90-degree angle, forming a square corner. We can identify these lines using angles and symbols in diagrams.

- Correct. The angle between a line and its perpendicular is 90 degrees.
- Actually, yes, lines that are perpendicular will always be at a 90 degree angle where they intersect.

Parallel lines are lines in the same plane that do not intersect. Line segments and rays that are parts of parallel lines are also parallel. What are parallel lines. Parallel lines are coplanar lines that are equidistant from each other throughout their entire lengths. Parallel lines never intersect. Some real life examples of parallel lines ...
Parallel lines are those lines that are always the same distance apart and that never meet. The symbol used to denote parallel lines is ||. Explore more about parallel lines, equations, and angles formed by parallel lines with concepts, illustrations, examples, and solutions.
