Final answer:
The question deals with determining triangle congruence using specific criteria: SSS, SAS, ASA, AAS, and HL. Each rule compares sides and angles of two triangles to ascertain their congruence. These criteria are essential in the study of geometry for comparing different triangles' shapes and sizes.
Step-by-step explanation:
The question pertains to the concept of triangle congruence, which is a fundamental aspect of geometry. In determining whether two triangles are congruent, mathematicians use specific rules based on the comparison of the triangles' sides and angles. These rules are the Side-Side-Side (SSS), Side-Angle-Side (SAS), Angle-Side-Angle (ASA), Angle-Angle-Side (AAS), and Hypotenuse-Leg (HL) congruence theorems.
SSS congruence criterion states that if the three sides of one triangle are congruent to the three sides of another triangle, then the triangles are congruent. SAS states that 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 signifies that if two angles and the side between them in one triangle are congruent to two angles and the intervening side of the other triangle, the triangles are congruent. AAS is where if two angles and a non-included side in one triangle are congruent to two angles and the corresponding non-included side in another triangle, the triangles are congruent. The HL theorem is specifically for right triangles and states if the hypotenuse and one leg of a right triangle are congruent to the hypotenuse and one leg of another right triangle, then the triangles are congruent.
