use a protractor and a ruler
I generally use a pencil and ruler. To construct the right angle to draw it I also use compasses. To measure the right angle to draw it I also use a protractor.
to construct an angle of 20 degrees all you have to do is to trisect an angle of 60degrees
With the ruler and compass construct a right angle isosceles triangle with a base of 9 cm At 4 cm from the LHS or RHS of the base draw a line that meets the apex of the triangle The angle of this line will be 40 degrees because each 1 cm of base space represents 10 degrees when joined to the apex
use trisection method

by using a ruler and a compass
Construct 2 perpendicular lines which will meet at 90 degrees then by bisecting this angle wll give a 45 degree angle

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
Use a ruler to make a right angle triangle of dimension 3,4,5 the angle adjacent to the side of 4 units length is 30 degrees.

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.
Yes. First draw a perpendicular (90 degrees) and then bisect the angle.
You cannot, you must use a protractor.
Construct a circle and divide the circumference into 36 equal arcs Each arc will represent 10 degrees and 11 of them subtended to the circle's centre will create an obtuse angle of 110 degrees
Construct a 90 degree angle isosceles triangle which will have equal sides and then divide the base into 9 equal parts joining the parts by lines to the apex of the trangle. Each line represents 10 degrees and 8 lines will equal to 80 degrees.
