Definition & Meaning
Parallel lines are lines in a plane that never meet or intersect, no matter how far they are extended. They maintain a constant distance apart and are characterized by having the same slope in a Cartesian coordinate system. Proportional parts refer to segments that are in a constant ratio to each other, often observed in triangles when parallel lines intersect the sides of the triangle. This concept is crucial in geometry as it helps in understanding relationships between different geometric figures.
