# Question: What Is Special About Parallel Lines?

## What are the characteristics of parallel lines?

Parallel lines are lines in a plane that are always the same distance apart.

Parallel lines never intersect.

Perpendicular lines are lines that intersect at a right (90 degrees) angle..

## What are parallel lines in an equation?

Two lines are parallel if the have the same slope. Example 1: Find the slope of the line parallel to the line 4x – 5y = 12. To find the slope of this line we need to get the line into slope-intercept form (y = mx + b), which means we need to solve for y: The slope of the line 4x – 5y = 12 is m = 4/5.

## What is an example of a line in real life?

Examples of Line Segments In Real Life Real-world examples of line segments are a pencil, a baseball bat, the cord to your cell phone charger, the edge of a table, etc. Think of a real-life quadrilateral, like a chessboard; it is made of four line segments.

## How do you explain parallel lines to kids?

What is parallel?Parallel lines are straight lines that always stay the same distance from each other and never meet:Children learn the names of shapes in Key Stage 1. … In Year 3 they need to identify parallel and perpendicular lines..More items…

## When can two lines become parallel?

Two lines are parallel if and only if they lie in the same plane and do not intersect. Parallel lines never cross. Parallel lines are always the same distance apart, which is referred to as being “equidistant”.

## Why are parallel lines important?

Parallel Lines are of critical importance when marking out roads, pedestrian crossings, car parks, and airport runways. Parallel Lines are also vital on basketball, tennis, volleyball, netball, badminton, and squash courts, as well as on atheletics tracks.

## What do parallel lines represent?

In geometry, parallel lines are lines in a plane which do not meet; that is, two straight lines in a plane that do not intersect at any point are said to be parallel. Colloquially, curves that do not touch each other or intersect and keep a fixed minimum distance are said to be parallel.

## What are the types of angles in parallel lines?

Angles that are in the area between the parallel lines like angle H and C above are called interior angles whereas the angles that are on the outside of the two parallel lines like D and G are called exterior angles. Angles that are on the opposite sides of the transversal are called alternate angles e.g. H and B.

## How are parallel lines used in real life?

Parallel line examples in real life are railroad tracks, the edges of sidewalks, marking on the streets, zebra crossing on the roads, the surface of pineapple and strawberry fruit, staircase and railings, etc.

## What are parallel lines give 2 examples?

Real-Life Examples of Parallel Lines Buildings are erected with walls parallel to each other, ceilings are parallel to floors, and one building is usually put up parallel to other buildings on the same block. Notebook paper is a thick collection of parallel lines.
