Square ABCD has coordinates A (−10, 5), B (10, 5), C (10, 0), and D (−10, 0). Square AꞌBꞌCꞌDꞌ has coordinates Aꞌ (−10, −5), Bꞌ (10, −5), Cꞌ (10, 0), and Dꞌ (−10, 0). Square AꞌꞌBꞌꞌCꞌꞌDꞌꞌ has coordinates Aꞌꞌ (−2, −1), Bꞌꞌ (2, −1), Cꞌꞌ (2, 0), and Dꞌꞌ (−2, 0).

Which transformations describe why squares ABCD and AꞌꞌBꞌꞌCꞌꞌDꞌꞌ are similar?

A.
Square ABCD was reflected across the x-axis and then dilated by a scale factor of to form square AꞌꞌBꞌꞌCꞌꞌDꞌꞌ.

B.
Square ABCD was dilated by a scale factor of and then rotated 90° counterclockwise to form square AꞌꞌBꞌꞌCꞌꞌDꞌꞌ.
