Step-by-step explanation:
Right triangle ABC is reflected over AC to form triangle AFC.
Triangle AFC dilated by a scale factor of two-thirds to form triangle DEC.
Reflection is a rigid transformation which preserves lengths and angles, then
Dilation is a transformation which maps the triangle into similar triangle, so
Thus,
Similar triangle have congruent corresponding angles, so
and proportional corresponding sides
Thus, correct options are:
