One vertex of a triangle is located at (0, 5) on a coordinate grid. After a transformation, the vertex is located at (5, 0). Which transformations could have taken place?

One vertex of a triangle is located at (0, 5) and the vertex after transformation is located at (5, 0).

This transformation could be a rotation:

R O, 270° (x, y).

(rotation with a center at origin, 270° counterclockwise).

or : R O, - 90° (x, y) (90° clockwise)

The triangle was refrected over the line y = x.
