NO LINKS Decide if each pair of triangles below is similar. If the triangles are similar, justify your conclusion by stating the similarity condition you used. ​Part 1

Step-by-step explanation:

  a. AA

  b. no (sides are not proportional)

Step-by-step explanation:

a. Two angles are marked as congruent. The triangles are similar by the AA postulate.

__

b. The side ratios 6 : 8 : 11 and 15 : 20 : 33 are both in reduced form. They are clearly not identical, so sides are not proportional. The triangles are not similar.

∠1≅∠2 by the alternate exterior angles theorem.

step-by-step explanation:

given, a ∥ b and ∠1 ≅ ∠3 .we have to prove that e ∥ f

we know that ∠1≅∠3 and that a || b because they are given. we see that by the alternate exterior angles theorem. therefore, ∠2≅∠3 by the transitive property. so, we can conclude that e || f by the converse alternate exterior angles theorem.

we have to fill the missing statement.

transitivity property states that if a = b and b = c, then a = c.

now, given ∠1≅∠3 and by transitivity property ∠2≅∠3 .

hence, to apply transitivity property one angle must be common which is not in result after applying this property which is ∠1.

the only options in which ∠1 is present are ∠1 and ∠2, ∠1 and ∠4

∠1 and ∠4 is not possible ∵ after applying transitivity we didn't get ∠4.

hence, the missing statement is ∠1≅∠2.

so, ∠1≅∠2 by the alternate exterior angles theorem.
