It is impossible to draw a straight line.
Draw any finite line. Write C near one end; write D near the other end. You now have a line segment and have named it CD.
I'd prefer to draw it with a pencil.
We are not here to do your homework for you.

It is impossible to draw a straight line.
A "line" does. A "line segment" does not. Most people interpret "line" to mean "line segment" (without realising it) and so would conclude that a line does not go on forever. A "line segment" is a line between two points, which is what you would draw if told to draw a "line" on a piece of paper.
7 cm line segament
First of all draw a line segment that is about 2 cm long between two points P0 and P1. At the one of the outer points, draw another line that is at an angle of 90 degrees from the first line segment. This will cause the new line segment to stand straight on the first segment. Draw another line segment between the not used endpoint of the new line segment, let's call it P2, and the not used endpoint of the first line segment. This will create a triangle. Now on the P2 endpoint, draw another line segment that is again at 90 degrees angle. Repeat the previous steps and you will have created a root spiral.
Two points with a single line connecting them.
Draw any finite line. Write C near one end; write D near the other end. You now have a line segment and have named it CD.

Draw a straight line segment. From one of its ends, draw another straight line segment. From the end of this straight line, draw another straight line segment which does not touch any of the existing lines. Repeat the same 5 more times. From the end of this last line, draw a straight line to the start of the first line. You may need to tweak some of the intermediate lines so that the last line does not intersect an existing line. That is it! A plane area enclosed by 9 straight lines = a 9-sided polygon.
It would look like a hut.
Draw a line segment with a straight edge.Place protractor on line segment with the center point on the end of the line and the line lined up with the bottom guide.Place a small dot on the 50o mark on the protractor.Place the straight edge on the end of the line segment and on the dot and connect the two.
