Multiple Choice
Is triangle ABC congruent to triangle EFG? Justify your argument.
No; AC ≠ FG, so SSS congruence is not met.
No; BC ≠ FG, so SSS congruence is not met.
Yes; all corresponding sides have the same measure, so SSS congruence is met.
Yes; all corresponding sides have the same measure, so by the definition of congruent figures, △ABC ≅ △EFG.
