Answer 1

The first step in constructing a perpendicular bisector typically involves placing the compass point on one endpoint of the line segment and drawing an arc that crosses the line segment at two points. Given the descriptions you've shared, the option that describes a compass needle on point A and the compass pencil placed about two thirds of the way along line segment AB sounds like it is indicating the initial setup, but it doesn't seem to align with standard terminology for this construction step.

However, based on typical construction steps, the correct response showing the first step would likely be the one that directly involves using a compass to create arcs. Therefore, the correct answer would be the diagram that describes two arcs being created (the last one you provided) since that indicates the beginning of the process to create a perpendicular bisector, even though it mentions it being bisected.

If you need to select just based on the provided descriptions without the visual cues, the key is to look for the construction involving placing the compass and drawing arcs. So based on this reasoning, I would suggest option D as it indicates the compass's involvement in constructing the bisector.
