Answer:
C
Explanation:
This is showing Side Angle Side congruency because first of all where the triangles connect shows vertical angles meaning that they are congruent
Second of all the triangle are similar because or proportions
![(9)/(6) =1..5\\(6)/(4) =1.5](https://img.qammunity.org/2022/formulas/mathematics/high-school/o09c9tz8219r6hcmnzeolbsnhob47jpg0j.png)
they are both showing proportions of 1.5 therefore the sides are similar
