Answer:
- Railway lines are example of parallel lines
- The floor and the walls of a room are example of perpendicular lines
- Two roads crossing at a signal can be termed as example of intersecting lines
Step-by-step explanation:
The lines can be related in following three ways
- Lines can be parallel
- Lines can be perpendicular
- Lines can be intersecting at an angle other than 90.
Now three real life examples of above three scenarios are described below:
- Railway lines are example of parallel lines
- The floor and the walls of a room are example of perpendicular lines
- Two roads crossing at a signal can be termed as example of intersecting lines
The square root of 10 because
sqrt(10) ^2 * 3.14 =
10*3.14 = 31.4
