To construct geometrical shapes
The compass is used to measure angles. The straightedge is used to draw a straight line. The two items together, are used to measure and draw angles and lines in geometric drawings.
Very much so in certain aspects of geometry.
a straightedge need not have measuring increments (inches, centimeters, etc.) while a ruler is a straightedge with measuring increments
You don't need advanced algebra to prove that it is impossible to trisect a line segment using only a straight edge and a compass: anyone knows that you will also need a pencil! And one you have that then there are plenty of easy ways to do it.
Yes, but you will also need a pen or pencil. Also, if the line segment is very long (eg 5 metres) you may have difficulty in finding a compass that will do the trick!

We need compass to know the direction we are going.

If a person is traveling they would need to know how to read a map, and what the symbols mean. The Compass Rose, is a compass. It gives a map reading direction, from where they currently are, to their end destination.
Because if you need to use your compass to figure out which direction is north,then you need to know by how much the direction the compass points is wrong,and which way. That's the magnetic declination.
If you need to know your way get a compass today.
You need a compass rose so you know which direction the map is. Without knowing the direction of the map you will be going in the wrong direction.

Yes. People (and vehicles) still need to know where they are going.
