Label each pair of triangles with the postulate or theorem that proves the triangles are congruent.

We can conclude that Δ ABC ≅ Δ DEF by AAS postulate.

Step-by-step explanation:

Δ ABC and Δ DEF are congruents because:

1. Their non-included sides BC and EF are equal (7 units = 7 units)

2. Their angles ∠A and ∠D are equal (39° = 39°)

3. Their angles ∠C and ∠F are equal  (64° = 64°)

Now, we can conclude that Δ ABC ≅ Δ DEF by AAS postulate.

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
