A’’B’’C’’.

Tip: In the above example, we performed the transformation and the parallel

the same time, if you want. To do so, input both the matrix [[1, 0], [0, −1]] and the

vector [1, 1] in step 4, and then tap [OK]. This will produce the result shown in

step 9.

operations on the selection as a single entity.
