What role so familiar places have in understanding situation of unfamiliar places

We can find unfamiliar places using familiar ones by understanding the location of the familiar ones.

Explanation:

Let us consider a place that is very familiar. As it is familiar to us, we do understand the route properly. With this route, we can find an unfamiliar place nearby.

Since we know the route of the familiar place, we can find a similar route for the unfamiliar place too. This makes the unfamiliar place as a familiar one.

We can try the same things using an example as follows:

Two girls were riding bicycles in familiar routes. They marked the source and destination where they knew the single route. They wanted to find new routes to the destination. Both of them started at the source and cycled the new route with the help of old route and reached the destination.

This strategy helps us to know the unfamiliar ones with the direction of familiar ones.
