When analyzing a situation with more than one line, the lines themselves can be classified according to their position or the angle they form when they intersect.
Distinct parallel lines are lines that never intersect and are always the same distance apart.
Parallel lines have the same slope but have no points in common. For example, the two metal rails of a railroad are parallel lines: they can stretch for kilometres without meeting.
To know how to draw parallel lines:
Constructing Parallel Lines
Coincident lines are lines that have exactly the same slope and that overlap their entire length.
In other words, they are two straight lines which, when superimposed, form a single line.
Intersecting lines are lines that intersect at a single point.
The point where two or more straight lines meet is called the intersection point.
Perpendicular lines are lines that intersect at right angles.
By deduction, perpendicular lines are also intersecting lines. However, they have one specific characteristic: they meet at a 90° angle.
To know how to draw perpendicular lines:
Constructing Perpendicular Lines
To algebraically analyze the relationships between lines when we have the general or functional form of a rule:
