What is a notable feature of dividers as measuring devices?

Dividers are primarily designed to transfer distances and make measurements in a precise manner without directly providing a numerical reading. When used, dividers consist of two sharp points that can be placed at specific locations on a scale or drawing. While they allow for accurate transfers of distances, they do not give a numerical output or reading in the way that calipers or measuring tapes do. Instead, the user often measures with the dividers in relation to a scale or other measuring device to determine the actual distance, underscoring their role as a tool for comparative measurement rather than direct reading.

The other options suggest features that inherently conflict with the fundamental purpose and function of dividers. For instance, features such as providing secondary readings or automatic adjustments do not apply to dividers as they are manually operated tools that rely on user input for measuring distances or transferring measurements. Measuring angles is also beyond the typical use of dividers, which are more focused on linear measurements rather than angular relationships.
