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.

The converse is also true: if two lines have equal corresponding angles, the lines are parallel. The angles that fall on alternate sides of a transversal and between the parallels (called alternate angles) are equal.

In the figure below, line “AB” is parallel to the line “CD”. The perpendicular distance is always the same between two parallel lines. Sides of various shapes are parallel to each other. In the rectanglegiven below, the single arrow lines are parallel to each other, and similarly, the double arrow lines are also parallel to each other. Parallel lin...
A transversal is a line that intersects two parallel lines (or lines on a plane) at different intersecting points, forming angles.
Parallel lines can be easily identified using the following fundamental properties and characteristics: 1. They are always straight lines with an equal distance between each other. 2. They are coplanar lines. 3. They never intersect, no matter how far you try to extend them in any given direction. 4. If there is a transversal line that intersects t...
Linear equations are generally described by the slope-intercept represented by the equation y=mx+b. Where “m” is the slope, “b” is the y-intercept, and y and x are variables. The value of “m” determines the slope and indicates the steep slope of the line. Note that the slopes of the two parallel lines are always the same. For example, if the slope ...
Example 1: Find out which lines are parallel to each other in the given figure. Solution: All the three lines with arrows passing through them are parallel to each other, which means: a || b || c Lines with the double arrows, i.e., line d and e are transversals of lines a, b, and c, but they are parallel to each other. So, we can say that d || e Ex...
Any two lines are said to be parallel if the Alternate exterior angles so formed are equal. Any two lines are said to be parallel if the Consecutive interior angles on the same side of the transversal are supplementary.
Two lines are said to be parallel when they do not meet at any point in a plane. Lines which do not have a common intersection point and never cross path with each other are parallel to each other. The symbol for showing parallel lines is ‘||’. Two lines which are parallel are represented as:
- 2 min
- Parallel lines are those lines on a plane that do not meet each other at any point. They are non-intersecting lines.
- Parallel lines are always equidistant apart from each other. They do not intersect each other. When cut by a transversal, parallel lines form a pai...
- Given, x and y are pairs of interior angles on the same side of transversal, hence they are supplementary. x + y = 180 ° Also, x and y are equal....
- If one of the pair of angles is 45 degrees, then its corresponding angle is also equal to 45 degrees.
- If one of the pairs of angles is 108 degrees, then its vertically opposite angle is also equal to 108 degrees.
Jun 4, 2024 · Parallel lines symbol is denoted as || as they never meet each other or intersect each other no matter how long they are extended. So, the symbol used to denote the parallel lines is ||. For instance, if AB is parallel to XY, we write it as AB || XY. Parallel Lines Formula.
Sep 5, 2021 · If two lines are parallel then their corresponding angles are equal. If the corresponding angles of two lines are equal then the lines must be parallel. Example \(\PageIndex{2}\)
