Clayton needs to reflect the triangle below across the line y = x. Which statements about the reflection are true? Check all that apply.

• Clayton could use the rule (y,x) to find the points of the image.

• The image and pre-image will not have the same orientation because reflections flip figures.

• C' will remain in the same location as C because it is on the line of reflection.

• C' will move because all point move in a reflection.

• The image and the pre-image will be congruent triangles.
