Question

Is ABC DEF? If so identify the similarity postulate or theorem that applies.

Answer 1

Answer: SAS (Apex)

Explanation:

Answer 2

B:Similar :SAS

Explanation:

The Angle-Side (SAS) Similarity Theorem states that 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 are similar.

In the given triangles <B=<E= 40 °

`(AB)/(DE) =(9)/(3)=(3)/(1)`

`(BC)/(EF)=(15)/(5) =(3)/(1)`

Or,
`(AB)/(DE) =(BC)/(EF)`

Hence triangle ABC~ Triangle DEF by SAS similarity theorem.
