Triangle ABC is rotated 90 degrees about the origin to form triangle A’B’C’. Which composition of transformations on triangle ABC will result in a triangle in the same position as triangle A’B’C’?

Triangle ABC is transformed by a rotation about the origin, and then a translation. The first transformation is a rotation of degrees. The second transformation is a translation that moves units left and units down.

The composition ry-axisT(0, 2) is used to transform a triangle having a vertex at (0, 1). Describe how to find the coordinates of the image of this vertex.
