Trapezoid EFGH has coordinates E (−3, 4), F (1, 4), G (3, 1), and H (−5, 1). Trapezoid EꞌFꞌGꞌHꞌ has coordinates Eꞌ (−12, 16), Fꞌ (4, 16), Gꞌ (12, 4), and Hꞌ (−20, 4). Trapezoid EꞌꞌFꞌꞌGꞌꞌHꞌꞌ has coordinates Eꞌꞌ (12, −16), Fꞌꞌ (−4, −16), Gꞌꞌ (−12, −4), and Hꞌꞌ (20, −4). Which transformations describe why trapezoids EFGH and EꞌꞌFꞌꞌGꞌꞌHꞌꞌ are similar?

I didn't get any pictures only what I put here and I need to know if the first figure was rotated 90 degrees clockwise or 180 degrees counterclockwise

OpenStudy (triciaal):

suggest doing a sketch plot one point draw segment to the origin (0, 0) plot new location and view the change
