What is a tool for estimating angles in anchor systems?

In rope rescue, accurately estimating angles in anchor systems is critical for understanding how forces are distributed throughout the system. The correct choice, a peace sign, refers to a visual tool that can represent angle estimation. When creating a triangle with your fingers in the shape of a peace sign, it allows for a quick visual reference for approximating angles, particularly useful when setting up anchors in real-time situations where standard measuring tools may not be easily accessible.

Other options, while related to measuring or estimating, do not serve the same practical purpose in the context of rope rescue systems. An anchor gauge is designed for assessing the strength or testing the load of anchors rather than estimating angles. A protractor is an accurate tool for measuring angles but may not be practical in a dynamic rescue environment where quick, visual estimations are needed. A measuring tape is useful for linear measurements but does not provide an estimation for angles directly.
