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.
To draw a 70-degree angle, start by drawing a straight line using a ruler; this will be one side of the angle. Place a protractor's center point at one end of the line, aligning the baseline of the protractor with the line. Locate the 70-degree mark on the protractor and make a small mark. Finally, remove the protractor and draw a line connecting the end of the original line to the mark you made, forming the 70-degree angle.
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.
To draw a 65-degree angle, start by drawing a straight horizontal line using a ruler; this will be one side of the angle. Place a protractor on this line so that the center point of the protractor aligns with one end of the line. Find the 65-degree mark on the protractor and make a small mark above the line. Finally, remove the protractor and use a ruler to draw a line from the end of the original line to the mark, forming the 65-degree angle.
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.
