幸福

A specific method or technique used to perform an artistic or technical task. It refers to the specialized 'how-to' skills involved in creation, particularly in arts, crafts, and literature.

A formal term referring to an established system, method, or formula used to carry out a process. It describes a structured or technical approach rather than just a simple way of doing something.

A specific standard or technical specification used for industrial products, dimensions, or quality requirements. It ensures uniformity and compatibility between different items or systems.

Refers to a standard, level, or benchmark of quality, skill, or achievement. It is used to describe how high or low a certain state is compared to a norm or expectation.

A noun indicating the amount, level, or extent of a quality or condition. It is also frequently used as a suffix to mean 'approximately' or 'about' when referring to quantities or time.

Refers to a line or plane that is at a right angle (90 degrees) to a horizontal line or the ground. It describes a perfectly upright or 'plumb' orientation used in geometry, construction, and physics.

Refers to two or more lines or planes that are at a constant distance from each other and never intersect. It is also used metaphorically to describe situations where two parties fail to reach an agreement or where events occur simultaneously.

Refers to a diagonal relationship or position, specifically relating to opposite corners or angles in a geometric shape or a physical space. It is commonly used in mathematics to describe lines connecting non-adjacent vertices, as well as in daily life to describe sitting or standing diagonally across from someone.

The distance from the center of a circle to its outer edge. It is half of the diameter and is used in both mathematical contexts and to describe a physical area around a specific point.

The distance from one side of a circle to the other, passing through the center point. It is a fundamental measurement used in geometry and daily life to describe the size of round objects like plates or pipes.
