Help I don't understand this in the slightest bit!

Create a line segment, bisect it, create an angle, and bisect it.
Copy the line segment and angle from Part 1 using appropriate construction tools (either by hand or using a drawing program), and justify each step of your construction process.
Based on what you learned about constructions, use complete sentences to write a prediction of how you could copy a given triangle. Create a triangle and try to construct another triangle congruent to it. Justify each step of your construction. Then answer the following questions:

Did you accurately construct a triangle?
    What would you do differently next time you constructed it?
    Were you able to justify each step? Why or why not?

Well, I understand what a line segment and an angle are, what i'm confused about is how do you dissect each and what "construction" is...

this is a line
it is infinite and this infinite is represented with arrows |dw:1363819716867:dw|

this is a ray, it starts from a point and goes to infinity
|dw:1363819742630:dw|

this is a line segment, it is a line between 2 defined points, it is not infinite
|dw:1363819792629:dw|
