Answer:
The method you would use to prove the two Triangles is
AAS
Step-by-step 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}
