Jan 16, 2024 · Parallel lines are two lines in a plane that will never intersect (meaning they will continue on forever without ever touching). A key feature of parallel lines is that they have identical slopes.

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.
How do we know when two lines are parallel? Their slopes are the same! The slope is the value m in the equation of a line: y = mx + b. Example: Find the equation of the line that is: parallel to y = 2x + 1. and passes though the point (5,4) The slope of y = 2x + 1 is 2. The parallel line needs to have the same slope of 2.

Any two lines are said to be parallel if the Corresponding angles so formed are equal.
Solution: The two lines are parallel as they meet one of the properties of parallel lines “when the alternate interior angles are equal, the lines are parallel”. $∠a$ is equal to $∠c$, and both of these are alternate interior angles.
Answer: Yes, parallel lines can exist in three-dimensional space as long as they are in the same plane and never intersect, similar to how they exist in two-dimensional space. Learn Parallel Lines at Bytelearn. Know the definitions, see the examples, and practice problems of Parallel Lines.
If two lines are cut by a transversal and the alternate interior angles are congruent, then the lines are parallel. Visit BYJU'S to learn the properties of parallel lines.
