An example of a perpendicular line is a 4 way intersection at a stop sign. Another example would be a window that has 4 smaller squares in it.

A real life example of a segment bisector is a median of a road. A median is the physical barrier that divides two lanes of traffic heading in opposite directions. The median bisects the road meaning it divides the road into two equal parts. It is the perpendicular bisector of the segment formed by the two lanes of traffic.

The walls of most buildings are perpendicular to the ground they are built on.
Any measurement in which the direction is relevant requires vectors.
In real life unit vectors are used for directions, e.g east, north and up(zenith). The unit vector specifies the direction. Gyroscopes maintain a direction and keep things level. Whenever and where ever location is important, unit vectors are a part of real life. Whenever directions are important in your real life, then unit vectors are important. If everything was confined to move along a straight line, then unit vectors would not be important. If you can move in a plane, then unit vectors are important. Moving in space, unit vectors are more important. cars, ships and planes all move in space. Controlling and tracking these all involve unit vectors.

Anything that's moving involves vectors in some way. My favorite example is if you're walking in a given direction, and someone is approaching you perpendicularly, and you slightly speed up or slow down to avoid colliding with them.

stand up... that is a perpendicular line right there. you are 90 degrees with respect to the floor.
