Question

Does the construction demonstrate how to copy a segment correctly by hand?

Answer 1

Answer:

• No, it does not, because the segments do not have the same length.

Explanation:

The segment AB is supposed to be copied.

The correct procedure is:

1. Put the tip of the compass on the point A
2. Open the compass till the point B
3. Without changing the width of the compass, put the tip of the compass on point C.
4. Draw an arc from C.
5. Draw a line from C until a point in the arc.
6. Mark and label the point of intersection as D.
7. Done.

Doing that, the length of the new segment CD equals the length of the segment AB.
