The compass needles are both magnets on very free suspensions. Bring two of them together, and they forget all about the earth's magnetic field, and they instantly swing to point at each other.
You will need... A set of compasses (for drawing the circle), and a straight edge. First, draw the circle. Then - put the point of the the compasses on the line. Mark the circle where the pencil crosses it. Place the point on this intersection and repeat the action until you're back at your starting point. Now - using the straight edge, join every alternate point to each other - forming an equilateral triangle.
Yes, a line and a point can be on the same line. A point can be placed on a line. It will then be collinear.
Where the decimal is placed you just have to bring it straight down.
When you multiply decimals, the decimal point is placed in the product.
They both forget about which way is North, and the needles point at each other.

North
The needle in compasses is magnetic and is drawn to the Earth's magneticism in the North. When the needle is placed near a metal, as all magnets are, attracted to metals.
The emblem most recognizably associated with Freemasonry is called the square and compasses. It consists of a right angled square set on its point like a letter "V" and a pair of compasses opened to about 45 degrees above it. In some jurisdictions the letter "G" is placed in the space between the square and the compasses. If you find the website of any Masonic Lodge you will see this logo.
They use the fact that the earth acts as a giant magnet so that compasses point towards the north pole.

because of the earth's magnetic core
No. If you are talking about magnetic compasses, they are aligned with the Earth's magnetic field, which is not exactly north-south (depending where on the Earth you are located). There are, however, special compasses that make use of the Earth's rotation; those will point north-south, regardless of the magnetic field.No. If you are talking about magnetic compasses, they are aligned with the Earth's magnetic field, which is not exactly north-south (depending where on the Earth you are located).

A compass rose is the name given to the face of a compass on which the points and direction names are printed. Some compasses rotate the whole compass rose, with direction read off a fixed point in the housing. Other compasses have a fixed compass rose and use a free spinning magnetic needle on a pivot to point towards magnetic north.
Without magnetic metal or other magnets nearby to deflect them, magnetic compasses point exactly tothe earth's north magnetic pole. The user must be aware that the north magnetic pole is not located atthe earth's north geographic pole, and make the necessary correction in order to find the true geographicdirections from his location.
Magnetism. The compass aligns with the magnetic field of the Earth.
