In which of the following ways do you know that two triangles are similar but do not know if they are congruent?

Question

SSS, AA, ASA, HL, SAS

Answer 1

AA Similarity Postulate: If two angles of one triangle are congruent to two angles of another, then the triangles must be similar.

 

SSS Similarity Postulate:  If the lengths of the corresponding sides of two triangles are proportional, then the triangles must be similar. 

 

SAS Similarity Postulate: If an angle of one triangle is congruent to an angle of a second triangle and the lengths of the sides including these angles are proportional, then the triangles must be similar.
