When using a counterexample to prove a conditional statement false, which must be true about the counterexample? there must be infinite counterexamples the counterexample must satisfy the hypothesis of the conditional statement. there must be at least one example under which the conditional statement is true. the counterexample must satisfy the conclusion of the conditional statement.

Which statement is true? the given sides and angles cannot be used to show similarity by either the sss or sas similarity theorems. the given sides and angles can be used to show similarity by the sss similarity theorem only. the given sides and angles can be used to show similarity by the sas similarity theorem only. the given sides and angles can be used to show similarity by both the sss and sas similarity theorems.

How do you use the elimination method for this question? explain, because i really want to understand!
