SSS Similarity Criterion : If the corresponding sides of two triangles are proportional;then they are similar

Theorem 6.4 : If in two triangles, sides of one triangle are proportional to (i.e., in the same ratio of ) the sides of the other triangle, then their corresponding angles are equal and hence the two triangles are similiar

SAS Similarity Criterion: If in two triangle; one pair of corresponding sides are proportional and the included angles are equal then two triangles are similar.
