How does a compass help you draw a line?
Spring.
Trisecting a line segment requires a ruler and compass since a straightedge and compass will not be sufficient?
false
True or false trisecting a line segment requires a ruler and compass since a straight edge and compass will not be sufficient?
False
How do you construct angle120 degrees with using a compass?
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.
It is possible to trisect a line segment using only a straightedge and compass?
True
What is the name of the line with which a compass aligns?
A needle
1 What is the name of the line with which a compass aligns?
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.
How does a needle on a compass align itself?
if a bar magnet swings freely it will act like a compass.
What are facts that proves the earth is a magnet?
- A compass needle always aligns along the north-south line - The earth stays in its orbit
What magnetized steel needle that aligns with the magnetic of the earth is a?
compass
What is the name of the line which a compass align?
A needle
What happens to a compass when it is brought near a current-carrying wire?
the compass aligns with the magnetic field created by the wire
What makes compasses point to the North pole?
Magnetism. The compass aligns with the magnetic field of the Earth.
How does a compass needle align itself?
A compass has a needle that is magnetized. This needle is suspended so that it can rotate freely and it can align itself with any magnetic field it is exposed to.If you put a magnet close to a compass, the needle will align itself with the magnets magnetic field.It picks up the earth's magnetic field.answer 2 A magnetic compass needle aligns itself with the lines of magnetic force at your locality.It picks up the earth's magnetic field.answer 2 A magnetic compass needle aligns itself with the lines of magnetic force at your locality.
What direction does a compass needle point if a current carrying wire is wrapped around it?
The compass needle aligns itself parallel to the direction of the lines of magnetic force where it happens to be. It does not 'point to a particular pole' for that is beyond the sensibility of a simple bar of metal. I repeat, it aligns itself parallel to the lines of magnetic force ...
How does a compass needle align its self?
The compass needle is magnetic, so it aligns itself with the magnetic poles. For more information on magnetic fields, see http://en.wikipedia.org/wiki/Magnetic_field
A compass is a scientific instrument used to locate the what?
The magnetic north pole of the Earth.add. Actually the compass aligns itself with the lines of magnetic force at your location. From this we may infer the direction of the magnetic poles.
