Is it possible to contruct a equilateral triangle with a straightedge and a compass?
Yes definitely. Draw a line. Set the compass to the length of that line. Place the point of the compass on one end of the line and prescribe an arc. Place the compass on the other end of the line and prescribe a second arc which intersects the first arc. Where they meet, draw lines to each end of the first line and you will have an equilateral triangle.
When Trisecting a line segment requires a ruler and a compass since a straight edge and compass will not be sufficient?
False
How do you use a ruler and compass to construct an equilateral triangle with sides of lingth 6 cm?
Draw a straight line 6cm long. Put the compass point at one end of the line and extend the compass to the other end of the line. Draw an arc of this radius from each end of the line, Join the point where the arcs intersect to each end of the the line and ypu have your equilateral triangle.
How do you make a 80 degree angle using a ruler and a compass?
Draw a point, and a long straight line through it. Put the centre of the compass over the point, with north on the compass (or zero degrees) on the line. Then draw a second line out from the point at 80 degrees on the compass. You'll then have a 80 degree angle between the lines. It's usually a trick that teachers decide to do on their pupils. A compass is what you use to find north and a pair of compasses is used to draw circles.
What is the French name for compass?
a compass is called "une boussole" (fem.) in French.
What is the name of the line with which a compass aligns?
A needle
What is the name of a 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.
What is the name of the line which a compass align?
A needle
What magnetized steel needle that aligns with the magnetic of the earth is a?
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.
How does a needle on a compass align itself?
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.
What is the moveable bar in a compass called?
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.
What makes compasses point to the North pole?
Magnetism. The compass aligns with the magnetic field of the Earth.
What are the parts of magnetic compass?
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.
Does a compass contain a magnet?
Yes, a compass typically contains a magnetized needle that aligns itself with the Earth's magnetic field to point towards magnetic north.
Which compass is pointing in the correct direction?
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.
Which metals do not effect a compass?
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.
