teräväkäräisiin

Teräväkäräisiin is a Finnish term that translates to "sharp-pointed" or "acute-angled". It is primarily used in the context of geometry to describe angles that measure less than 90 degrees. In Finnish mathematical terminology, an angle is classified as teräväkäräinen if its measure is between 0 and 90 degrees, exclusive. This is equivalent to the concept of an acute angle in English.

The term can also be applied to shapes that possess sharp corners or vertices. For example, a polygon with many sharp angles could be described as having teräväkäräinen muoto (a sharp-pointed shape). In a more general sense, outside of strict mathematical definitions, it can refer to anything that has a pointed or sharp extremity, such as a tool with a sharp tip or a pointed architectural feature. The adjective emphasizes the degree of sharpness or the acute nature of a point or angle.
