Symmetry of a 5×5 matrix. In linear algebra, a symmetric matrix is a square matrix that is equal to its transpose. Formally, is symmetric {\displaystyle A {\text { is symmetric}}\iff A=A^ {\textsf {T}}.} Because equal matrices have equal dimensions, only square matrices can be symmetric.

We explain what a symmetric matrix is. Also, you'll find examples of symmetric matrices and all the properties of this type of matrices.
A symmetric matrix is a square matrix that is equal to its transpose. For a matrix A to be symmetric, it must satisfy the condition: A ⊤ = A. This means that for all elements a i j of the matrix, the following condition holds: a i j = a j i.
Symmetric matrices appear in geometry, for example, when introducing more general dot products v Av or in statistics as correlation matrices Cov[X k,X l] or in quantum mechanics as observables or in neural networks as learning maps x sign(Wx) or in graph theory as adjacency matrices.
A symmetric matrix is symmetrical across the main diagonal. The numbers in the main diagonal can be anything, but the numbers in corresponding places on either side must be the same. In the correct answer, the matching numbers are the 3's, the -2's, and the 5's.
