diagonaalsed
Diagonaalsed is an Estonian term referring to diagonals or diagonal-related properties in mathematics. The concept appears in both geometry, where it describes line segments connecting non-adjacent vertices of polygons, and in linear algebra, where it relates to the diagonal elements of matrices and to diagonalization.
In geometry, a diagonal of a polygon is a line segment that joins two vertices that are
In three dimensions, the term can extend to space diagonals, which connect opposite vertices of polyhedra. For
In linear algebra, diagonaalsed relates to diagonal elements of a square matrix. The main diagonal consists
