Answer 2

The method you would use to prove the two Triangles is

AAS

Explanation:

Given:

First label the figure

∠ A =∠ D = 60°

∠ B =∠ E = 40°

BC = EC = 10

To Prove:

Δ ABC ≅ ΔDEC

Proof:

In Δ and Δ

∠ A ≅ ∠ D ……….{Given measure of each angle is 60°}

∠ B ≅ ∠ E ……….{Given measure of each angle is 40°}

BC ≅ EC ………...{Given measure of each side is 10 units}

∴ Δ ABC ≅ Δ DEC ….{By Angle-Angle-Side test}
