Understanding Parallel Lines

In geometry, parallel lines are lines in a plane that never meet; that is, they do not intersect or touch at any point. On a two-dimensional plane, parallel lines have the same slope. Given two lines in the form of linear equations:

Line 1: a1x + b1y = c1

Line 2: a2x + b2y = c2

These lines are parallel if and only if the ratio of their 'a' coefficients is equal to the ratio of their 'b' coefficients, which can be mathematically expressed as:

a1 * b2 = a2 * b1

This tool helps you quickly verify if two lines are parallel by entering the coefficients and visualizing them on a graph. Understanding parallel lines is fundamental in geometry and has applications in various fields, including architecture, engineering, and computer graphics.
