c sas
d no

question 6 (3 points)
are the triangles similar? select sss, aa, sas, or no.

a sss
b aa
c sas
d no

Explanation:

Step1: Check first triangle pair

We compare the ratios of the two given sides:
$\frac{4}{1} = 4$, $\frac{12}{3} = 4$
The included angles are equal (marked congruent). This matches the SAS similarity criterion.

Step2: Check second triangle pair

Two pairs of corresponding angles are marked congruent. This matches the AA similarity criterion, as two congruent angles are sufficient to prove triangle similarity.

Answer:

First question: c. SAS
Second question: b. AA
