Answer:
Your answer is C
Explanation:
The definition of similarity is when one shape can become another after a resize, flip, slide or turn.
If you multiply AD, which is 6, by 1.5 you get 9. Which is the length AC.
If you multiply AE, which is 10, by 1.5 you get 15. Which is the length of AB.
Both triangles share angle A, so that leaves you with SAS Similarity.
