Which tool is a large L-shaped square used in framing to check right angles?

• A. Framing Square
• B. Speed Square
• C. Measuring Tape
• D. Needle Nose Pliers

Answer: (A)

The essential idea is recognizing which tool is built to verify right angles in framing. A framing square is a large L-shaped tool with two arms that meet at a 90-degree corner. It’s designed specifically to check and lay out true right angles in structural work—helping ensure walls, headers, and joints are square and true. The longer arm and shorter arm give you a clear 90-degree reference, and many framing squares also include handy marks for common angles and stud layouts.

In contrast, a speed square is a smaller, triangular-shaped tool used for quick angle checks and layout on the job site, but it isn’t the large L-shaped framing square referenced here. A measuring tape is for length, and needle-nose pliers are for gripping and manipulating small parts, not for checking angles.
