which transformations could have occurred to map ABC ?

Answer:Option 4:  a Dilation and a Rotation.Step-by-step explanation:Given:  ΔABC and ΔA"B"C.ΔABC is transformed into ΔA"B"C with C as common vertexClearly from figure ∠A and ∠A" are reflected and switched the positions up to down. Since, positions are changed so it would be done by  Rotation. Also from Figure the image ΔA"B"C is  smaller than ΔABC, which shows dilation of the ΔABC.Therefore, correct option is 4 i.e.,  a Dilation and a Rotation.
