Triangle ABC is transformed by P'y-axis Orx-axis to get
triangle A"B"C".

1. The first transformation is a ;
(Reflection/translation/rotation)
2. The second transformation is a (translation/rotation/reflection)
3. For each point (x, y) on triangle ABC, the points on
triangle A'B'C" would be represented by (-x, y) (y, x) (-x, -y) or (-y, -x)

4. An equivalent rotation to the two composed
transformations is a rotation by (90 degrees/ 180 degrees/ 270 degrees/ 360 degrees)
