Question

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

Answer 1

We can conclude that Δ GHI ≅ Δ JKL by SAS postulate.

Explanation:

Δ GHI and Δ JKL are congruents because:

1. Their sides GH and JK are equal (9 units = 9 units)

2. Their included angles ∠G and ∠J are equal (62° = 62°)

3. Their sides GI and JL are equal (17 units = 17 units)

Now, we can conclude that Δ GHI ≅ Δ JKL by SAS postulate.
