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.

Joaquin is constructing the perpendicular bisector of line AB. What should be his first step?
Place the point if the compass on point B and draw an arc across AB.
How do you draw a rhombus using a compass?

What instrument do you use to draw circles?
A compass

How do you draw a diameter of circle?
Construct a circle with a compass and then draw a straight line through its centre
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.
How do you construct 80 degree angle using compass and ruler?
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.

How do you draw a perpendicular line which divide a line in to equal parts?
Use a ruler to measure the line (horizontal?) and mark the middle of the line, then use a right-angle triangle to draw a vertical line 90 degrees from the mark. Or you can use a compass fitted with a pencil to draw arcs that will give the middle mark and a mark to line a ruler against to draw the perpendicular line required. Search Google for using a compass.
What is the different steps in bisecting a line?
1. first draw a line any measurements 2. then get your compass and place it on the left side of your line remembering that the compass has to be more than halfway open then go up to the middle with ur compass and draw one half of a cross with the compass then draw another half a cross below the line not changing the width of the compass but make sure it is in line with the other half cross now take the compass of your page now place the point on the other side of the line and do the same as i just said then you should get two crosses one above the line and one below the finishing touch is get a ruler and where the crosses meet draw a line strainght the way down and then your done i hope that helped i learnt it in a maths lesson
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 divide a circle in to 6th equal parts?
If you have a protractor: Draw a line from the center of the circle to the outside (radius), then measure 60 degrees and draw another line. If you have a compass: Draw a circle using the compass, then, using your compass, place the compass needle on the edge of the circle, draw another circle (KEEP THE RADIUS THE SAME). Your two circles should have two intersection points. Place the needle on one of the intersection points and repeat the process. I suggest you look at:
How can a compass help in math?
A compass can be used to calculate distance by angle and to help draw circles as well as finding the radius, diameter, and circumference of the circle.
Draw a triangle with equal sides?
Draw a straight line. Set a compass to the length of the line. Scribe an arc from each end of the line so the arcs intersect. Draw straight lines from each end of the original line to the intersection point
How do you draw an eqilateral triangle?
The answer depends on what tools you have. (a) you have a protractor: Draw a straight line of the required length. At each end draw an angle of sixty degrees so that the rays are (i) on the same side of the first line and (b) moving towards each other. If necessary extend them so that they meet. The first line and these two form an equilateral triangle. (b) you have a compass: Draw a straight line of the required length. Put the point of the compass on on end of this line. Put the pencil point at the other end of the line and draw an arc. Switch the compass to the other end of the first line and draw another arc so that it crosses the first arc. The point where the two arcs cross, when joined to the two ends of the original line, will give an equilateral triangle.
