E (-3,4) is connected to F (1,4) which covers 4 units.....E2 (12,-16) is connected to F2 (-4,-16) which covers 16 units...
563blackghost (563blackghost):
Now we need to input that into a ratio so...\[\frac{ 16 }{ 4 }=4\] so the scale factor is 4
563blackghost (563blackghost):
so which answer choices can we cross off?
OpenStudy (narissa):
a and c?
OpenStudy (narissa):

its 90?
563blackghost (563blackghost):
i think its 180 degrees counterclockwise because the shape is turned 180 degrees instead of 90 degrees
OpenStudy (narissa):
