A line cannot be bisected since it is of infinite length. A line segment can be bisected, but I don't see a protractor as being the best tool for that. You may have meant angle instead of line (?)
Bisect a segment is to divide the line segment into 2
A midpoint is in the middle of the line but does not bisect it because it is just a point on that line and does not cross the line.
It is the line from 0 to 130 degrees on your protractor
First, draw a line. Then, using a protractor, depending on what type of protractor you have, make a mark next to the 100° mark or 10° away from 90°. Finally, draw another line.
Draw a line of any length. Set the protractor at one end of this line and draw an angle of 60 degrees - measuring angles from the other end of the line. Move the protractor to the other end of the original line and repeat. If necessary extend the lines of the angle until they meet. The three lines will form a regular (equilateral) triangle.
A protractor.
To accurately measure angles using a protractor, place the center of the protractor on the vertex of the angle. Align one side of the angle with the zero line on the protractor. Read the measurement where the other side of the angle intersects the protractor scale.
With a protractor and a straight edge or bisect an angle of 75 degrees.

Use a protractor or bisect a 45 degree angle with a compass and a straight edge

Draw a line. Draw a perpendicular to that line then a perpendicular from that one.
Draw a straight line and place zero degrees of the protractor at the endpoint of the line then mark out 135 degrees and join the endpoint with the marked out degrees to construct the required angle.
Draw a line of any length. Set the protractor at one end of this line and draw an angle of 60 degrees - measuring angles from the other end of the line. Move the protractor to the other end of the original line and repeat. If necessary extend the lines of the angle until they meet. The three lines will form a regular (equilateral) triangle.
I am preparing to bisect these parallel lines.
