Question

Medal! Is it A or B?





Triangle ABC is similar to triangle AꞌꞌBꞌꞌCꞌꞌ.

Which transformations were performed on triangle ABC to produce triangle AꞌꞌBꞌꞌCꞌꞌ? All dilations have a center of dilation at the origin and all rotations are around the origin.



A.
Triangle ABC was reflected across the x-axis and then dilated by a scale factor of 2 to form triangle AꞌꞌBꞌꞌCꞌꞌ.

B.
Triangle ABC was dilated by a scale factor of 2 and then rotated 90° counterclockwise to form triangle AꞌꞌBꞌꞌCꞌꞌ.

C.
Triangle ABC was reflected across the y-axis and then rotated 180° clockwise to form triangle AꞌꞌBꞌꞌCꞌꞌ.

D.
Triangle ABC was dilated by a scale factor of 2 and then reflected across the y-axis to form triangle AꞌꞌBꞌꞌCꞌꞌ.
