To bisect an angle using a compass and ruler, start by placing the compass point on the vertex of the angle and drawing an arc that intersects both rays of the angle. Label the points where the arc intersects the rays as A and B. Next, without changing the compass width, place the compass point on point A and draw an arc inside the angle. Repeat this step from point B, creating two intersections of the arcs. Finally, use the ruler to draw a straight line from the vertex of the angle through the intersection of the two arcs, which will bisect the angle.
no
Any angle can be bisected using a compass and a straight edge.
Yes
create a 'v' parralel to the 'v' of your angle using the width of your ruler, join the two apexes and continue the line to biscect the angle.
To construct a 37.5-degree angle using a ruler and compass, start by drawing a straight line and marking a point A on it. Then, construct a 60-degree angle at point A by drawing an arc from A, marking points B and C where the arc intersects the line, and connecting A to B. Next, bisect the 60-degree angle by placing the compass point on B, drawing an arc that intersects the angle, and marking those intersection points. Finally, draw a line from A through the intersection of the arcs to create a 30-degree angle, then bisect the 30-degree angle to obtain the desired 37.5-degree angle.

use trisection method
Its true just got it wrong
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
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.
first draw a ray .
Yes, you can bisect an angle using the paper folding technique.
