Kõrvaldiagonaalid

Kõrvaldiagonaalid refers to the diagonals of a square or rectangle that run from the bottom-left to the top-right corner or from the top-left to the bottom-right corner. In contrast, the main diagonal typically refers to the one running from the top-left to the bottom-right corner. For a square or rectangle with vertices labeled A, B, C, and D in a clockwise or counterclockwise manner, the main diagonal could be AC, while the other diagonal would be BD. These are sometimes called the anti-diagonal or counter-diagonal, especially in contexts like matrix operations where diagonals have specific meanings. In geometry, both AC and BD are simply diagonals of the quadrilateral. The term "kõrvaldiagonaalid" is less common in standard Euclidean geometry texts and may appear in more specific mathematical discussions or translated materials. Understanding which diagonal is being referred to often depends on the context or a defined convention within a particular problem or field.
