Answer 1

See attached image

Explanation:

With this type of reflection, one has to convert the points of the form (x, y) into (y, x).

So the vertices of the triangle will transform the following way:

(4, 4) into image (4, 4)

(4, 1) into image (1, 4)

(2, 1) into image (1, 2)

Please see attached picture to find the new reflected triangle depicted in red.
