To identify the diagram that depicts the first step in constructing a perpendicular bisector, you typically want to look for a diagram that includes the following elements:
- A line segment that you want to bisect.
- Two arcs drawn from each endpoint of the line segment, indicating the intersection points above and below the segment.
This first step involves placing the compass on one endpoint of the line segment, then drawing an arc that crosses over the line segment. After that, you would repeat the process from the other endpoint, ensuring that both arcs overlap.
If you can provide the diagram options, I'd be happy to help you identify the correct one!
