Question

question 9 (1 point)
(01.02 mc)
does the construction demonstrate how to copy a segment correctly by hand?
a yes, the compass was kept at the same width as segment ab to create the arc from point c
b yes, a straightedge was used to create ray c.
c no, the compass was not kept at the same width as segment ab to create the arc from point c.
d no, a straightedge was used to create ray c.

Explanation:

To copy a segment correctly by hand, we use a compass to measure the length of the original segment (in this case, segment \(AB\)) and then keep the compass at that same width to create an arc from the starting point of the new segment (point \(C\)). A straightedge is used to draw the ray, but that's not the critical part for copying the length. In the given construction, the compass was not used correctly (as the length from \(C\) to \(D\) does not match \(AB\) as per the correct copying - with - compass method).

Answer:

C. No, the compass was not kept at the same width as segment AB to create the arc from point C.
