Answer 1

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 $a_8$).
