Question

definition of parallel line and perpendicular line
​

Answer 1

Answer:

If two line shaving same slope then those are said to be parallel. if the angle between the two lines is 90° then those are said to be perpendicular, in this case product of slopes equal to -1

Step-by-step explanation:

Answer 2

Hello

Here is your answer

Answer:

PARALLEL LINES :

Parallel lines are two lines that are always the same distance apart and never touch. In order for two lines to be parallel, they must be drawn in the same plane, a perfectly flat surface like a wall or sheet of paper. ... Any line that has the same slope as the original will never intersect with it.

PERPENDICULAR LINES :

In elementary geometry, the property of being perpendicular (perpendicularity) is the relationship between two lines which meet at a right angle (90 degrees). The property extends to other related geometric objects. A line is said to be perpendicular to another line if the two lines intersect at a right angle.
