Asquare matrix is called a permutation matrix if it contains the entry 1 exactly once in each row and in each column, with all
other entries being 0. all permutation matrices are invertible. find the inverse of the permutation matrix

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
