In your own words, explain how to copy a line segment.

Answer 1

The trick is to use 2 triangles .Line 1 to the line. Set the other one against another side. Slip it.

Answer 2

I will only give you a hint about this...the question asks you to think about it and explain in your own words.

Hint: you will need a compass.

Also, classically Euclid considered a compass to be collapsible, but demonstrated that a line segment could be copied with such a compass.
