NEED HELP ASAP!!!
Triangles 1 and 2 can be shown to be congruent using the reflection
A) (x,y) → (-, -y).
B) (x,y) → (-x, y).
C) (x,y) → (-7, x).
(x, y) (y,x).
The answer is B because you have to reflect the triangle over the X-axis. For instance, point (-1,1) is on triangle 1 while (1,1) in on triangle 2. Therefore, only the X coordinate changes. So the answer is b
