SSS refers to the Side-Side-Side postulate, which is a theorem in geometry used to determine congruence of triangles. According to the SSS postulate, if the lengths of the corresponding sides of two triangles are equal, then the triangles are congruent.

To illustrate, let’s consider two triangles ABC and DEF. If we know that side AB is equal to side DE, side BC is equal to side EF, and side AC is equal to side DF, we can conclude that triangle ABC is congruent to triangle DEF.

This postulate is based on the fact that if all three sides of a triangle are equal to the corresponding sides of another triangle, then all corresponding angles will also be equal. Extending this, we can say that if all three sides of a triangle are equal to all three sides of another triangle, all corresponding angles will be equal, and thus the two triangles are congruent.

In a mathematical proof, the SSS postulate can be used to justify the congruence of triangles when given the lengths of their sides.
