Final answer:

To prove that two triangles are congruent, one can apply the SAS, ASA, HL, or SSS theorems, but the choice depends on the specific information known about the triangles. Each theorem requires knowledge of certain combinations of sides and angles to establish congruence conclusively.

Step-by-step explanation:

To prove that two triangles are congruent, you can use one of several theorems depending on the information given about the triangles. Here are the options and their conditions:

  • SAS (Side-Angle-Side): If two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the triangles are congruent.
  • ASA (Angle-Side-Angle): If two angles and the side between them in one triangle are congruent to two angles and the side between them in another triangle, then the triangles are congruent.
  • HL (Hypotenuse-Leg): In right triangles, if the hypotenuse and one leg of one triangle are congruent to the hypotenuse and one leg of another triangle, the triangles are congruent. This is a specific case of the SAS postulate that applies only to right triangles.
  • SSS (Side-Side-Side): If all three sides of one triangle are congruent to all three sides of another triangle, then the triangles are congruent.

Without additional specific information about the triangles in question, it is not possible to determine which statement to use; each of these theorems requires certain types of measurements to be known. However, these are the standard methods for proving triangle congruency in geometry.
