What is the primary purpose of a speed square?

Measuring materials
Cutting angles
Adjusting screws
Ensuring angles are square

The correct answer is: Ensuring angles are square

The primary purpose of a speed square is to ensure angles are square, which is critical in carpentry and construction. The speed square, also known as a framing square or triangular square, is a triangular tool that helps determine and check 90-degree angles. When constructing structures, it is essential to ensure that frames, walls, and other components are square to maintain stability and proper alignment. By placing the tool on the materials to be joined, a carpenter can easily verify that the angle is correct, which aids in achieving accuracy in measurements and cuts. This prevents issues later in construction, such as misalignment and structural weaknesses. While the other options may describe functions related to measuring or cutting, they do not capture the fundamental and specialized role of the speed square in ensuring squared angles necessary for solid construction practices.
