Which tool is described as identical to the standard speed square but adds a variable angle protractor?

• A. Angle Finder
• B. Chalk Line
• C. Adjustable Speed Square
• D. Bevel Gauge

Answer: (C)

A tool that preserves the familiar speed square shape but adds a variable angle protractor is designed to measure and transfer any angle while keeping the quick right-angle and 45-degree references intact. The standard speed square gives a reliable 90-degree corner and a 45-degree line, which lets you lay out square and bevel cuts fast. By adding an adjustable protractor, you can set any angle you need and scribe or align saws precisely to that angle without swapping tools. The other tools don’t combine a square body with a built-in adjustable angle, so they don’t offer the same seamless capability. Chalk lines mark straight lines, not angles; a bevel gauge measures angle between two surfaces but isn’t a square with an integrated protractor; an angle finder measures angles but isn’t built into the square form for quick layout.
