How can you tell if it's a sas (side angle side) or sss (side side side) or asa (angle side angle)?

The SSS rule states that :

If three sides of one triangle are equal to three sides of another triangle, then the 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.

The ASA rule states that :

If two angles and the included side of one triangle are equal to two angles and included side of another triangle, then the triangles are congruent.
