Answer 1

The Option is D) ΔDEC ≅ ΔDEA

ΔDEC ≅ ΔDEA ….{By Side-Angle-Side Congruence Statement}

Explanation:

Given:

AE ≅ EC

∠AED ≅ ∠CED = 90°

To Prove:

ΔDEC ≅ ΔDEA

Proof:

In ΔDEC and ΔDEA

AE ≅ EC ……….{Given}

∠AED ≅ ∠CED …………..{measure of each angle is 90°}

ED ≅ ED ……….{Reflexive Property}

ΔDEC ≅ ΔDEA ….{By Side-Angle-Side Congruence Statement}
