Choose 1 answer: Choose 1 answer: (Choice A) A Alycia used an invalid reason to justify the congruence of a pair of sides or angles. (Choice B) B Alycia only established some of the necessary conditions for a congruence criterion. (Choice C) C Alycia established all necessary conditions, but then used an inappropriate congruence criterion. (Choice D) D Alycia used a criterion that does not guarantee congruence.
