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.
How do you make 82 degree angle with compass?
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!

Compass compass compass
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?
first you draw a circle, divide it into 4

How do you draw a diameter of circle?
Construct a circle with a compass and then draw a straight line through its centre
How do you construct 32 degree angle using ruler and compass?
Well, honey, you start by drawing a line with your ruler. Then, you put the point of your compass on one end of the line and draw an arc. Next, you put the point of your compass on where the arc intersects the line and draw another arc. Where those arcs meet is your 32-degree angle. Voila!
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 construct 54 degree angle with compass?
To construct a 54-degree angle with a compass, start by drawing a straight line using a ruler. Place the compass on one endpoint of the line and draw an arc that intersects the line. Without changing the compass width, place the compass on the intersection point and draw another arc. Where the two arcs intersect is a point that, when connected to the endpoint of the line, forms a 54-degree angle.
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.
