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

Answer:

AA Similarity Postulate

Step-by-step explanation:

we know that

If DE is parallel to BC

then

[tex]m<ADE=m<ABC[/tex] ------> by corresponding angles

[tex]m<AED=m<ACB[/tex] ------> by corresponding angles

therefore

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