To determine the appropriate triangle congruence criterion to state that two triangles are congruent, we need to understand the definitions of each criterion:
-
SSA (Side-Side-Angle): Not a valid congruence criterion because it can produce ambiguous cases (triangle could be formed in two different ways).
-
ASA (Angle-Side-Angle): Valid criterion where two angles and the included side are known.
-
AAS (Angle-Angle-Side): Valid criterion where two angles and any side not between them are known.
-
SAS (Side-Angle-Side): Valid criterion where two sides and the included angle are known.
Given this information, you would use:
- ASA if you know two angles and the included side,
- AAS if you know two angles and a non-included side,
- SAS if you know two sides and the included angle.
If you identify which pieces of information you have about the triangles, you can choose the correct option from the list. If specific information about the triangles was part of your question, please provide that to give a targeted recommendation.
