Answer:
- Reflexive property of congruence
- SSS congruence postulate
Step-by-step explanation:
The property of congruence that says an object is congruent to itself is the reflexive property.
When the three sides of a triangle are shown congruent to the three corresponding sides of another triangle, the SSS (Side-Side-Side) congruence postulate can be invoked to claim the triangles are congruent.
