Perpendicular Lines And Intersecting Lines

Parallel and Perpendicular Lines

Ii lines in a plane either come across on extending or do not meet at all.

Parallel lines

Lines in a plane that never encounter, fifty-fifty if we extend them, are chosen parallel lines. Equally they never meet, the distance between the parallel lines remains constant.

For instance:

Case 1: In the given picture show, the rails of the railroad runway represent parallel lines as the altitude between the rails remains the aforementioned.

Example two: Lines of a writing pad are another example of parallel lines.

Example 3: In the given picture parking line stripes show parallel lines.

Intersecting Lines

Lines which run into or appear to come across when extended are chosen intersecting lines and the bespeak where they meet is chosen the bespeak of intersection.

Perpendicular Lines

Lines which run across (intersect) each other at correct angles are called perpendicular lines. In geometry, perpendicular lines are represented using the symbol ''.

For instance:

Example 1: The given picture shows the perpendicular lines in the flooring tiles.

Example 2: In the given movie, the vertical and the horizontal lines (black and pink) in the English alphabet 'H' are perpendicular lines.

Through the given diagram, we tin can visualize the difference between perpendicular and non-perpendicular lines.

Fun Facts:
1. Have yous ever wondered why 90° is called a right angle? When ii lines intersect each other, they form ii angles, and when the angles formed are equal, and then information technology is a fair or "right" situation. This is the reason we telephone call 90° every bit a right angle.
2. An easy way to remember parallel lines is to call up of "equal to (=)" sign.
