Definitions [2]
Definition: Parallel Lines
Parallel lines are straight lines that never intersect and remain at a constant distance from each other.
They are denoted by the symbol “∥”, meaning ‘is parallel to’.
Examples: Railroad tracks, Zebra crossings, Staircase steps
Definition: Perpendicular Lines
When two lines intersect, and the angle between them is a right angle, then the lines are said to be perpendicular.
In mathematics, the relationship of perpendicularity is denoted by the symbol ⊥.
If Line A and Line B are perpendicular, the relationship is written as AB ⊥ PQ.
