The Vietnamese word "đường kính" translates to "diameter" in English. It is a term used primarily in geometry and science.

Basic Explanation:

• Meaning: "Đường kính" refers to the length of a straight line that passes through the center of a circle and connects two points on its circumference. Essentially, it measures how wide the circle is.

Usage Instructions:

• Use "đường kính" when discussing circles, spheres, or any round objects where you need to measure or describe their width.
• It can be used in both everyday situations (like measuring a pizza) and more formal contexts (like scientific discussions).

Example:

1. Basic Example: "Đường kính của cái bàn này là một mét." (The diameter of this table is one meter.)

Advanced Usage:

• In technical contexts, "đường kính" can be used to describe not just circles but also spheres and cylindrical shapes (like pipes).
• It can also be used in mathematical calculations, such as finding the radius (which is half of the diameter).

Word Variants:

• Radius: The term "bán kính" refers to the radius, which is half of the diameter.
• Circumference: The term "chu vi" refers to the circumference of the circle, which is the distance around it.

Different Meanings:

• While "đường kính" primarily refers to diameter in geometry, it can also be used metaphorically in some contexts to describe the extent or width of non-physical concepts, like "the diameter of an issue" meaning the scope or scale of a problem.

Synonyms:

• Kích thước: This means "size" and can sometimes be used in contexts where dimensions, including diameter, are being discussed.
• Đường tròn: This translates to "circle" and is related but refers specifically to the shape rather than the measurement.
