# 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

Side-Angle-Side is a rule used to prove whether a given set of triangles are congruent. The SAS rule states that. If two sides and the included angle of one triangle are equal to two sides and included angle of another triangle, then the triangles are congruent. An included angle is an angle formed by two given sides.

if three sides of a triangle are equal to the three sides of another triangle then the two triangles are congruent . This is known as side-side-side theorem of congruence of triangles.

Hopefully u understood.
​I have tried my best to explain.
