- As we wrote earlier, an axiom of Euclidean geometry is that for every straight line and every point not on that line, there is one straight line that passes through that point, and never intersects the first line. Such lines are called Parallel lines. Parallel lines are always the same distance from each other.

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. Example 2.

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: This means that line AB is parallel to CD. The perpendic...
Lines can either be parallel or intersecting. When two lines meet at a point in a plane, they are known as intersecting lines. If a line intersects two or more lines at distinct points then it is known as a transversal line. In figure 2, line l intersects lines a and b at points P and Q respectively. The line l is the transversal here. ∠1,∠2,∠7 and...
As we have already learned, if two lines are parallel, they do not intersect, on a common plane. Now if a transversal intersects two parallel lines, at two distinct points, then there are four angles formed at each point. Hence, below are the properties of parallel lines with respect to transversals. 1. Corresponding angles are equal. 2. Vertical a...
Q.1: In the given figure, p || q and l is a transversal. Find the values of x and y. Solution: Since, 6x+y and x+5y are corresponding angles. 6 x + y = x + 5 y 6 x – x = 5 y – y 5 x = 4 y x = 4y/5 Now, 4x and 6x+y are linear pair of angles, so, 4 x + 6 x + y = 180° 10x + y = 180° 40y/5 + y = 180° 45y/5 = 180° 45y = 180 × 5 = 900° y = 20 x = (4 × 20...

Parallel lines are the lines that never intersect each other and are equidistant. Learn about parallel lines, transversal, properties, equations, examples & more.
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 · Two lines are parallel if they do not meet, no matter how far they are extended. The symbol for parallel is \(||\). In Figure \(\PageIndex{1}\), \(\stackrel{\leftrightarrow}{A B}\) \(||\) \(\stackrel{\leftrightarrow}{C D}\). The arrow marks are used to indicate the lines are parallel.
When lines never meet no matter how far they stretch, they're called parallel lines. To represent this in math, we use a special symbol: ∣∣. So, if we see parallel symbol like AB ∣∣ CD, it means line AB and line CD are parallel. On the other hand, if lines do meet, they're not parallel.
If two lines are parallel to the same line, they are parallel to each other. Parallel lines cut by a transversal have the following properties: Corresponding angles are congruent.
