Question

Please help/medals!

Answer 1

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?

Answer 2

B.
Trapezoid EFGH was dilated by a scale factor of 4 and then rotated 180° counterclockwise.

C.
Trapezoid EFGH was dilated by a scale factor of 1/4
and then reflected across the x-axis.

D.
Trapezoid EFGH was translated 4 units right and 4 units up and then rotated 180° clockwise.
