The ancient Greeks famously attempted to solve three classical problems using only a straightedge and compass: squaring the circle, doubling the cube, and trisecting an angle. Squaring the circle involves constructing a square with the same area as a given circle, which was proven impossible due to the transcendental nature of π. Doubling the cube and trisecting an angle also turned out to be impossible with those tools, as they require solutions that involve cube roots and specific angles that cannot be achieved through simple constructions.
Doubling a cube and trisecting any angle
Doubling a cube Trisecting any angle
The construction of parallel lines typically involves using a straightedge and a compass. One common method is to draw a transversal line and then, using the compass, measure equal angles from the transversal at the points where it intersects the original line. By marking these equal angles and connecting the points, you can create a second line that is parallel to the first. This ensures that the two lines will never intersect.
I believe you are referring to the word mnemonic which is a word or phrase which is designed to help you remember something. An example may be "Never Eat Soggy Waffles" for remembering the order of directions around a compass.
If they would intersect, that would mean that at one point in space, the field lines point to two different direction simultaneously. A compass needle would have to point to two different directions at once.

Squaring the circle, duplicating the cube, and trisecting an angle were constructions that were never accomplished by the Greeks with only a straightedge and compass. These are known as the three classical geometric problems that cannot be solved using only those tools.
Doubling a cube and trisecting any angle
The Greeks famously struggled with three classical problems: duplicating the cube, which involves constructing a cube with twice the volume of a given cube; trisecting an arbitrary angle; and squaring the circle, which entails constructing a square with the same area as a given circle. These constructions were proven impossible using only a straightedge and compass due to limitations in algebraic methods and the nature of the numbers involved. The impossibility of these tasks was established through the development of modern mathematics, particularly in the 19th century with the advent of field theory and Galois theory.

You should never see a fence on a compass.
A compass will never stop pointing north unless it is close to a magnet.
