i have problems in understanding sss rule

Dear Student,

If three sides of a triangle are equal to the three corresponding sides of another triangle, then the triangles are congruent.

For example, consider the following triangles ABC and PQR. You can verify by measuring the sides of these triangles that AB = PQ, BC = QR and AC = PR. Thus, by using SSS congruence criterion you can say that these triangles are congruent.

Regards
