I need help on 2 column proofs!!

The proof is given below.

Step-by-step explanation:

Given,

AB║DC and AB≅DC

To proof ΔABE ≅ Δ CDE

Proof:

AB║DC and AC is the transversal

∠BAE = ∠ECD ( alternate angle)

AB║DC and BD is the transversal

∠ABE = ∠EDC( alternate angle)

Now,

In ΔABE and Δ CDE

∠BAE = ∠ECD ( alternate angle)

∠ABE = ∠EDC( alternate angle)

∠AEB = ∠CED (vertically opposite angle)

So, by AAA condition we get,

ΔABE ≅ Δ CDE

b) the dogs need to shift their focus to human scent.
