We need the plimsoll line to show the legal amount of weight in case it has an overload and plus to show how high or low the water is to prevent sinking.
5 straight lines are needed to construct a pentagon.
There are several intersected lines.
12 lines
to lines that r the same length

the plimsoll lines are what is on the side on a boat. when you fill a boat with heavy goods, the water can be no higher than the line otherwise the boat sinks.
To help reduce the number of lives lost at sea due to overloading of ships.
Plimsoll lines are marked on the side of a ship to indicate maximum loading. This varies slightly depending on the season and the ocean, depending what type of ship it is.
The Plimsoll Lines stopped owners overloading the ship, as it provided a 'load line' which could not be exceeded. i.e. when a ship goes to sea, the water line is never allowed to go above the plimsoll line.
The plimsoll line is a reference mark painted on the bow of a ship. If the line is below the water level, the ship is overloaded. There are lines for when on fresh water and when on salt water.
The plimsoll line was invented in the 19th centary by a british man named Samuel plimsoll
