Final answer:
To construct segment XY, begin by drawing a ray with an endpoint labeled X or Y, then transfer the length of segment AB to the new ray using a compass to mark the other endpoint.
Step-by-step explanation:
The question pertains to the geometric construction of a line segment. Given that segment AB has already been constructed, the first step to construct segment XY is not detailed in your options, but typically involves drawing a ray with an endpoint labeled as either X or Y, from which you establish the length of the new segment based on the length of segment AB. The correct answer to the question provided would be:
A. Draw a ray and label the endpoint X or Y.
The construction process generally continues by transferring the length from segment AB to the newly drawn ray. This would involve using a compass set to the length of segment AB, placing the compass point on the endpoint X or Y, and drawing an arc that intersects the ray, marking point Y or X respectively to complete segment XY.
Note
: Be sure to double-check the question as it seems like a crucial part of the question concerning the specific construction steps of segment XY could be missing or unclear.
