Karen notices that segment bc and segment ef are congruent in the image below:
two triangles are shown, abc and def. a is at negative 2, 2. b is at negative 2, 4. c is at 0, 3. d is at 2, 1. e is at 2, 3. f is at 0, 2. angles c and f are shown as congruent.
which step could her determine if δabc ≅ δdef by sas?
∠f ≅ ∠a
segment ca ≅ segment df
∠e ≅ ∠c
segment ac ≅ segment df
