Find p-1, where p = [adg beh cfi] is orthogonal.

 The required inverse of the given matrix is

Step-by-step explanation:  We are given to find the inverse of the following orthogonal matrix :

We know that

if M is an orthogonal matrix, then the inverse matrix of M is the transpose of M.

That is,

The transpose of the given matrix P is given by

Therefore, according to the definition of an orthogonal matrix, the inverse of matrix P is given by

Thus, the required inverse of the given matrix is

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.
