Parallel Lines and Perpendicular Lines

 6.2 Parallel Lines and Perpendicular Lines

We will learn to recognize parallel lines and perpendicular lines.

 Parallel Lines If two straight lines are parallel, then the gradients are the same. The concept of parallel lines is that they always have the same distance from each other and do not intersect or meet.

EXAMPLE:

 Perpendicular Lines  The concept of a perpendicular line is two lines that meet or intersect with each other at a right angle (90°).
