Yes by bisecting an angle of 140 degrees with a compass
use trisection method
There are 60 minutes in 1 degree.
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.
its East...
pad khaoo !!
no
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
Yes by bisecting an angle of 140 degrees with a compass
By bisecting an angle of 164 degrees or use the compass with the help of a protractor.
Use a ruler
In conjunction with a straight edge and a protractor.
By bisecting a 15 degree angle with a straight edge and a compass.
use trisection method
bisect between 120 and 180 degree ( 120 + 180= 300/2 =150)
It is possible to construct a 20 degree angle using only Ruler and Compass. I happened to stumble across a method that is highly accurate. It is posted on my blog. Check the related link
