Answer:
b and c
Step-by-step explanation:
Given the triangles ABC and EDC
We will find the transformation that makes the triangles are similar
As shown: the triangles are reflected over the y-axis
the rule of the reflection over the y-axis will be as follows:

And as shown, the length of the side AB = 3 units
And the length of the side ED = 1 units
So,

So, the answer will be:
D) (x,y) ⇒ (-x, y)
E) (x,y) ⇒ (1/3 x, 1/3 y)
