No, it is impossible even with a straight ruler and compass.

Yes by trial and error.
Solution.
Strick an arc, from the apex of the angle. It will intersect the the two lines of the angle, now by trial and error get 3 equal segments of the arc, between the lines (hint use compass as divider).
You will need a straight edge or ruler to finish the trisection, and draw the angle too.

In general no. However you can trisect the angle 180 degrees. Although this barely counts since its essentially a straight line. I haven't tried it, but there might be a way to bisect these constructed angles and therefore trisect 90 degrees. And then again to trisect 45 degrees.
But in general they require constructing ratios outside the algebraic set of numbers which is the set you are limited to with these construction methods. I believe you can trisect an angle if you allow yourself a calibrated rule, or a tri-square.

i in my opinion hate interruptions which keeps me from answering exciting questions like this. the physique of concepts is trouble-free. 2/7 ? is the chord attitude of a heptagon, so first draw a circle, entice 3/7 ?, then use the compass to many times mark the chord lengths around the circle till there are 7 factors in it, at which you will have trisected the unique chord attitude 3/7 ?.

This is one of the classical problems from greek antiquity if you also allow an unmarked straightedge. It is impossible to trisect a general angle with these tools in a finite number of steps.
However, if you allow a *marked* straightedge, it is possible and this was known to Archimedes.

no u cannot trisect any angle with a compass

draw a perpendicular set of line. from the end of horizontal line mark an arc and then from the mid of line bisect it.
Follow that for vertical line too. But, the arc distance you have to take trial and error.
