you will have to construct a 135 degree angle first...but constructing a 90 degree with a 45 degree to give u the 135 degree angle and then using that as a reference, u will have to draw a 60 degree angle going counter clockwise from the 135 degree angle so that 135-60=55 degree...hahah
I know it is confusing but if only i could show you...cz i mean visual is better than oral right !??! haha ^D^...
hope i can help....
If you don't have a computer program that will do this for you, you need paper or other material to mark on, a straight edge, a protractor, and something to make marks with (pencil, pen, scribe, etc.)nb You can make a 30 degree angle with a straight edge and a compass (with a pen or pencil in it). You can also do it with a straight edge, pencil, and a string with the string and pencil acting as a compass.
First draw a 90 degree angle .Than draw a 20 degree angle from that 90 degree angle . Than the rest of the angle will be 90-20=70 .Now bisect the 70 degree angle we will get 70/2=35. Now add the rest of the angle means 35+20 =55 GOT 55 DEGREE ANGLE
By using a compass and a protractor and the reflex angle will be 10 degrees less of a full turn which is 360 degrees
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.
Easiest is to use a protractor. Alternative: Draw a 90 degree angle. Bisect the external angle so that it is 45 degrees. Trisect that angle so that the angle adjacent to the 90 degree angle is 15 deg Then 90 + 15 degrees = 105 degrees. Both, bisection and trisection require the use of a compass (and ruler).

Use a protractor.
You use a protractor
first draw a ray .
Yes by bisecting an angle of 140 degrees with a compass
Draw a line segment AB. Put your compass point at B and stretch the compass out until it is at point A. Now draw a circle. Now move the compass point to B, leaving the compass opening the same as before and draw another circle. The circles will intersect in two points. Call them C and D. Draw CD and name its intersection with AB as the point E. angle CEB is a right angle. Now you need to bisect the 90 degree angle you just constructed to get two 45 degree angles. Look in your book as to how to bisect an angle. The angle CAB = 60 degrees. So bisect it to get a 30 degree angle and then bisect it to get a 15 degree angle. You can get a 105 degree angle by adding the 90 degree angle and the 15 degree angle. Similarly, you can get a 75 degree angle by subtracting the 15 degree angle from 90 degrees. Look in your book on how to copy an angle.
In conjunction with a straight edge and a protractor
By bisecting an angle of 30 degrees using a compass and a straight edge
with compass.........at 90+60degree angle,,,,,,,,, * * * * * and 90 + 60 = 105??? You need to draw a 90 degree ange and bisect it to give a 45 deg angle. Then add a 60 degree angle. 45 + 60 = 105.
Oh, dude, it's like super easy. First, you draw a straight line. Then you put the pointy end of the compass on one end of the line and swing it around until it hits the line at 65 degrees. Boom, you've got yourself a 65-degree angle. Like, it's not rocket science or anything.
Construct 2 perpendicular lines which will meet at 90 degrees then by bisecting this angle wll give a 45 degree angle
First draw a 90 degree angle .Than draw a 20 degree angle from that 90 degree angle . Than the rest of the angle will be 90-20=70 .Now bisect the 70 degree angle we will get 70/2=35. Now add the rest of the angle means 35+20 =55 GOT 55 DEGREE ANGLE
