Question

how to draw an angle of 110 degrees using compass

Answer 1

hey mate here's your answer

Draw a line using the scale AB.  Then draw the perpendicular bisector CO for the line segment AB.  This can be done by compass and scale.

 Then use the standard procedure with compass and scale to trisect the angle AOC.  So then draw the lines OD and OE. They will be separated by 30 deg.

Now trisect again the angle DOC (of 60 deg).  Then we get the trisecting lines OF and OG. The angle between GO and OC is 20 deg.

Thus we have the angle  GOB = 110 deg.
