Which of the tools below lacks the ability to miter square?

1. Try square

2. Combination square

3. Carpenter's framing square

4. Both A and C

The correct answer is: Both A and C

The key to understanding this question lies in the functionality of each tool in relation to mitering, which is the process of cutting an angle, typically 45 degrees, for joining two pieces at a corner. The try square is primarily used for checking and marking right angles and ensuring wood is cut squarely. While it can be useful for those purposes, it is not designed specifically for miter cutting, which requires an adjustable angle setting. The carpenter's framing square, also known as a framing or framing triangle, is mainly used for layout work and ensuring that framing members are square to each other. It typically features a right angle but does not have the capability to set or measure adjustable angles, making it unsuitable for miter cuts. On the other hand, the combination square is designed with versatility and can measure both 90-degree and 45-degree angles. It includes a movable arm that adjusts to various angles, enabling it to effectively handle miter cuts. Therefore, the tools that lack the ability to miter square are the try square and carpenter's framing square. Selecting both these options highlights the limitation of these tools in performing miter cuts, effectively leading to the correct answer.
