Question

Select the postulate or theorem that you can use to conclude that the triangles are similar.

SAS Similarity Theorem

SSS Similarity Theorem

AA Similarity Postulate

Answer 1

You can use AA since the parallel lines make corresponding angles congruent.

Answer 2

Answer:

AA Similarity Postulate

Step-by-step explanation:

we know that

If DE is parallel to BC

then

$m<ADE=m<ABC$ ------> by corresponding angles

$m<AED=m<ACB$ ------> by corresponding angles

therefore

Triangles ABC and ADE are similar by AA Similarity Postulate (the three internal angles are congruent)
