first draw a circle at the point of the angle.
u will get 2 intersections where the circle and 2 lines meet
draw 2 arcs from the 2 points that u have, within the angle.
then u will notice the 2 arcs intersect each other.
from that point draw a straight line down to the point of angle
that will be your ans

It's impossible with a straight edge and compass, however it is possible with a scale (which I presume means a straight edge with marks on it) and compass. This website has a description of how to do it:

See the section Part IV - "Cheating" (violating the rules)

Take any snall radius with compass and draw an arc intersecting the two lines which subtend the angle.Keep the compass and draw an arc cutting the previous arc.Do the same with the other point.Join the intersection points with the vertex.

it's impossible for general case
