Steps:-)

Construct a line segment AB.

Point the compass on A and make an arc.

Name the intersection point of the line segment and the arc as C.

Point the compass on C and make another arc the intersects through A.

Name the intersection point of the two arcs as D.

Point the compass on D and the pencil on C and with the same length, again point the compass on D and make another arc.

Name the intersection point of the DC arc and the other arc as E.

Make another line segment intersecting A and E.

Now, name the ending point of the line segment as F and the measure of the constructed angle is 120*.
