namely

1, three groups of congruences of two equilateral triangles (SSS for short).

2. Two triangles with two sides and their included angles correspond to each other.

3. The consistency of two triangles with two angles and their clamping edges (ASA)

Note: S is the abbreviation of edge and A is the abbreviation of angle.
