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
To construct an angle of 142.5 degrees, you can start by drawing a straight line using a ruler. Then, using a protractor, mark a point on the line to serve as the vertex of the angle. Next, align the protractor so that the 0-degree mark is at one end of the line and the 180-degree mark is at the other end. Finally, mark a point at 142.5 degrees on the protractor, and draw a ray from the vertex through that point to create the angle of 142.5 degrees.
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.

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
