Final answer:
The correct answer is option (1) By its shape.A Phillips screwdriver is identified by its tip's cross shape, designed to fit Phillips screws' cross-shaped recess. Color and handle do not distinguish it from other screwdrivers.
Step-by-step explanation:
A Phillips screwdriver can be identified by the characteristic cross or '+' shape at the tip, which corresponds with the cross-shaped indentation found in the head of a Phillips screw. This design allows the screwdriver to grip the screw head's recess and apply greater torque without slipping. Moreover, the Phillips screwdriver's tip size varies to fit different sizes of Phillips screws, but the shape remains consistent. Screws in general, including Phillips-head screws, are usually made of metals such as steel, stainless steel, brass, or other alloys, selected for their strength and resistance to corrosion. Although screwdriver handles may come in various colors and sizes, these attributes do not distinguish a Phillips screwdriver from other types.
The Phillips screwdriver can be identified by its unique shape, specifically the cross-shaped head. Unlike flat-head screws that have a single linear slot, Phillips screws have two intersecting slots that form a cross. This design allows for better grip and torque when using a Phillips screwdriver to tighten or loosen the screw.
The color, size, and handle of a screwdriver can vary and are not specific indicators of a Phillips screwdriver. They can come in different colors and sizes to accommodate different types and sizes of screws. The handle can also be made of different materials, such as plastic or rubber, for comfort and grip.
