Answer:
X = -2
Step-by-step explanation:
Vertical lines go up and down. That means the x value is constant and the y value changes. We have an x value of -2
X = -2
Answer:
Δ HGI ≅ ΔEDF
Step-by-step explanation:
Given:
Δ DEF ≅ Δ GHI
From the given congruence statement we can figure out the corresponding sides that are congruent.
The arrangement shows:

So the rearranged statement can be written as:
ΔEDF ≅ Δ HGI
or
∴ Δ HGI ≅ ΔEDF
