Which of the following tools cannot make angular measurements?

The carpenter's level is primarily designed to determine whether a surface is horizontal or vertical, ensuring that constructions are even and true. It achieves this through the use of a bubble vial that indicates levelness. While it can certainly help in the process of placing and aligning materials, it does not facilitate the measurement of angles.

In contrast, the sliding bevel allows for the transfer of angles, the carpenter's square is used to verify right angles, and the vernier caliper can measure dimensions and angles with precision. Each of these tools has a function related to angular measurements, which is not the case for the carpenter's level.
