First draw a horizontal straight line a b Put compass point on a (open compass approximately half the length of line a b - note: ensure the compass is not altered throughout the following). Draw an arc that cuts line a b at c. Put compass point on c and draw an arc from a to cut the first arc at d. Draw a straight line through a d to form a 60 degree angle. For a 120 degree angle, put compass point on dand draw an arc from a to cut the first arc at e. Draw a straight line from a through e to give a second angle of 60 degrees: 60 + 60 = 120 degrees.
Well, honey, making an 82-degree angle with a compass is as easy as pie. Just start by drawing a straight line with your ruler. Then place the point of your compass on one end of the line and swing an arc that intersects the line. Finally, use your protractor to measure the angle between the two lines, and voila, you've got yourself an 82-degree angle. Easy peasy lemon squeezy!

The name of the line for the compass alignment is the index line. The line and the numbers around the outside edge can be used to plot a course to a distant object.
A needle
A compass needle is a magnetized steel needle that aligns with the Earth's magnetic field. Its use allows for determining directions such as north, south, east, and west.
The movable bar in a compass is called the compass needle. It is typically a thin magnetized bar that aligns with the Earth's magnetic field to indicate direction.
A needle on a compass aligns itself with the Earth's magnetic field. The needle is magnetized, with one end pointing towards the Earth's magnetic north pole and the other end pointing towards the magnetic south pole. This alignment allows the needle to point in the direction of magnetic north.
Yes, a compass needle is essentially a magnet because it aligns with the Earth's magnetic field due to its magnetic properties.
The main parts of a magnetic compass include the magnetic needle, which aligns with the Earth's magnetic field to indicate direction, and the compass housing, which protects the needle and contains the compass card with directional markings. There is also a lubber line, which is used to read the compass card, and a bezel ring for adjusting the compass heading.
Magnetism. The compass aligns with the magnetic field of the Earth.
Yes, a compass typically contains a magnetized needle that aligns itself with the Earth's magnetic field to point towards magnetic north.
Metals like aluminum, stainless steel, and gold do not affect a compass because they are not magnetic. The compass needle aligns with Earth's magnetic field, so nonmagnetic metals do not interfere with its functionality.
The compass that accurately aligns its pointer with the Earth's magnetic field is pointing in the correct direction. This ensures that it provides accurate readings for navigation.
