Question

Determine the Theorem or Postulate that proves triangle

congruence. If the triangles cannot be proven congruent,
choose "not congruent."

Answer 1

SSS theorem

Explanation:

It is indicated in the image that 2 sides of the triangles are congruent, and the third side is shared, which makes the third side automatically congruent as well. Therefore, we can use the side-side-side theorem to prove that the triangles are congruent.
