Two square matrices
and
are called congruent if there exists a nonsingular matrix
such that
![]() |
where
is the transpose.
Congruent
Exactly equal in size and shape. Congruent sides or segments have the exact same length. Congruent angles have the exact same measure. For any set of congruent geometric figures, corresponding sides, angles, faces, etc. are congruent.
Note: Congruent segments, sides, and angles are often marked.
