Final answer:
1) 6 over 12 equals 3 over 6. The correct proportion is 6 over 12 equals 3 over 6.
Step-by-step explanation:
The correct proportion is:
1) 6 over 12 equals 3 over 6
To determine if two triangles are similar, we can compare their corresponding sides. In this case, we have the proportion 6 over 12 (the length of the corresponding sides of triangle wxz) equals 3 over 6 (the length of the corresponding sides of triangle xyz).
By simplifying this proportion, we get 1 over 2 equals 1 over 2, which is true. Therefore, the triangles are similar.
