Kulma

Kulma is a Finnish noun meaning angle or corner. It refers to the space between two intersecting lines or to the point where two lines meet, as well as the outside corner of an object. In everyday language, kulma can describe both interior and exterior corners, such as the corner of a room or the corner of a piece of furniture.

In geometry, a kulma denotes the figure formed by two rays that share a common endpoint. The size of a kulma is measured in degrees or radians. Angles can be described as small or large, and in mathematical contexts they are commonly classified by size and properties, including general categories such as acute, obtuse, right, and straight angles, depending on the measure and the context.

The word is used across fields that involve spatial reasoning and construction, including crafts, architecture, and carpentry, where references to angular joints and corners are common. In these domains, kulma often appears in phrases describing measurements, joints, or design features.

Etymology and usage notes: Kulma is a native Finnish word. Its exact historical origin is not widely documented in concise summaries, but it functions as the standard term for angle and corner in modern Finnish.
