Consider triangles ADC and BEC.

1. BE⊥AC (statement
a_0) and AD⊥BC;

CB≅CA (statement
a_1)

Reason: Given.

2. ∠ADC (statement
a_2) and ∠BEC are right angles.

Reason: Perpendicular lines form right (statement
a_3) angles.

3. ∠BCE (statement
a_4) = ∠ACD (statement
a_5)

Reason: Reflexive Property of Congruence (statement
a_6).

4. ΔADC≅ΔBEC (statement
a_7).

Reason: HA Postulate (statement
a_8).
