Multiple Choice: Which property below can be used to prove that the triangles at right are similar?

$\text{AA}\sim$

$\text{SAS} \sim$

$\text{SSS}\sim$

$\text {HL} \sim$

none of these

Two triangles. The first triangle has two adjacent sides, 6, and, 9, with an angle between with 1 tick mark. The second triangle has two adjacent sides 6, and, 4, with an angle between with 1 tick mark.

Answer:

(b) because there are two sets of proportional sides

$\left (\frac{4}{6}\approx 0.66 \text{ and }\frac{6}{9}\approx 0.66\right )$

with a congruent angle between them.
