Parallel lines are the lines that never intersect each other and are equidistant. Learn about parallel lines, transversal, properties, equations, examples & more.
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.
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.

- All perpendicular lines are intersecting lines , but not all intersecting lines are perpendicular lines.
- Transversals are basically lines intersecting 2 or more lines. There may or may not be employments utilizing this skill, but nevertheless it is ver...

- The symbol ⊥ is the *perpendicular sign* - it shows that two lines are perpendicular to each other. For example: _line_ AB ⊥ _line_ CD. Hope this h...

- 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.
- Are you referring to what Sal was doing starting at 0:39? You are correct that CD is perpendicular to ST, but at the moment Sal was demonstrating t...

Parallel Lines. 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: Example 1.
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 \ (\overleftrightarrow {AB}\) and \ (\overleftrightarrow {CD}\) are parallel.

Parallel lines are lines that are lying on the same plane but will never meet. Understanding what parallel lines are can help us find missing angles, solve for unknown values, and even learn what they represent in coordinate geometry.
