The Vietnamese word "đa diện" primarily means "polyhedron" in English, which refers to a three-dimensional shape made up of flat surfaces (called faces) that are polygons.

Basic Explanation:

"Đa diện" is used in geometry to describe shapes like cubes, pyramids, and octahedrons. Each shape has multiple sides, and they can be regular (where all faces are the same) or irregular.

Usage Instructions:

• You can use "đa diện" when discussing mathematics, architecture, design, or any context that involves three-dimensional shapes.
• It can be used both in formal and informal settings, depending on the context.

Example:

• In a sentence: "Hình khối lập phương là một loại đa diện." (The cube is a type of polyhedron.)

Advanced Usage:

• In mathematics, you might encounter terms like "đa diện lồi" (convex polyhedron) and "đa diện lõm" (concave polyhedron), which describe the curvature of the shape.
• In architecture: "Nhiều công trình hiện đại sử dụng các dạng đa diện để tạo sự độc đáo." (Many modern buildings use polyhedral shapes to create uniqueness.)

Word Variants:

• "Đa diện" can be combined with other words to form phrases, such as:
  • "Đa diện hình học" (geometric polyhedron)
  • "Đa diện đều" (regular polyhedron)

Different Meanings:

While "đa diện" mainly refers to geometric shapes, it can also be used metaphorically in Vietnamese to describe something that has multiple aspects or dimensions, such as a person's personality or a complex situation.
