Question

problem 12: select which shortcut can be used to prove that this pair of triangles is congruent. if no method applies, choose
one.\ a b c d e side - side - side

Explanation:

Step1: Analyze SSS criterion

SSS requires all 3 sides equal.

Step2: Check triangle markings

Not all 3 sides are marked equal.

Answer:

We need more information about the markings on the triangles to determine the congruence - shortcut. If we assume from the visible markings (one side - pair marked equal and right - angles), if the other side - pair is also equal, it could be Hypotenuse - Leg (HL) for right - triangles. But without seeing all options and full markings, we can't be sure. If we only consider the given option "Side - Side - Side (SSS)", we need all three sides of one triangle to be equal to the corresponding three sides of the other triangle. Since we don't see all three sides marked equal, based on the information we have, the answer is none if only considering SSS.
