In the context of triangle similarity, what is the role of the included angle in SAS similarity?

• It must be proportional to the corresponding angle in the other triangle

• It must be congruent to the corresponding angle in the other triangle

• It must be smaller than the corresponding angle in the other triangle

• It does not affect the similarity
