Answer:

The correct order is step 1 → 4 → 2 → 5 → 6 → 7 → 8 → 3 → 9

Explanation:

1.
\overline{FA}\cong \overline{FB}


\overline{FA}\perp\overline{DB}


\overline{FB}\perp\overline{AC}

4. ∠FAB ≅ ∠FBA - In a triangle, angles opposite of congruent sides are congruent

2.
\overline{AB}\cong \overline{AB} - reflective property

5. ∠BCA is a right angle - Perpendicular lines for right angles

6. ∠ADB is a right angle - Perpendicular lines for right angles

7. ∠ADB ≅ ∠BCA - All right angles are congruent

8. ΔADB ≅ ΔBCA - AAS

3. ∠CAB ≅ ∠DBA- Corresponding part of congruent triangles are congruent (CPCTC)

9.
\overline{EA}\cong \overline{EB} - In a triangle sides opposite of congruent angles are equal.
