Question

Which theorem or postulate proves that △ABC and △DEF are similar? ​ AA Similarity Postulate ​ ​ SSS Similarity Theorem ​ ​ SAS Similarity Theorem ​

Answer 1

Which theorem or postulate proves that △ABC and △DEF are similar?

• SAS Similarity Theorem

$\sf \: AB\:and\:DE [Side] \\ \sf∠B\:and\:∠E[Angle] \\ \sf \: BC\:and\:EF [Side]$

• The ~ symbol represents similarity

Answer 2

The theorem that proves that △ABC and △DEF are similar is; SAS Similarity Theorem

What is the congruence postulate?

From the given triangles △ABC and △DEF, we see that the corresponding angles ∠B and ∠E are equal.

Now, we can see that sides in △DEF are a third of the corresponding sides in △ABC.

Thus, we can say that AB is congruent to EF.

Therefore both triangles are congruent by SAS Similarity Theorem
