Which term is a tool for determining stairway angle accurately?

• A. Measurement Sheet
• B. Angle Chart
• C. Chassis Installation
• D. Cleanup

Answer: (B)

Determining stairway angle accurately relies on a reference tool that directly translates measured dimensions into a slope or angle reading. An angle chart does exactly that: it provides angles corresponding to different rise and run combinations, so you can read off the stair angle from the measurements or verify that the stair geometry matches the design. This makes it quick and reliable, helping ensure the stairway meets safety and design requirements.

A measurement sheet, while useful for recording the actual rise and run, does not itself give the angle and requires additional calculation. Chassis installation and cleanup relate more to construction and maintenance tasks rather than determining the stair angle.
