triangles 1 and 2 can be shown to be congruent using the reflection
a) (x, y) → (-x, -y).
b) (x, y) → (-x, y).
c) (x, y) → (-y, x).
d) (x, y) → (y, x).

answer:

a.

step-by-step explanation:

congruent means the same/ equal like vertical lines, corresponding, and

reflection is easy all you have to do is reflect over the x- axis if it says reflect over the x- axis formula: ( keep x, change ,y)(x,-y)

y- axis is the same way with the formula (keep y, change ,,y)

i know cause recently is learning this in school, i past that subject already.
