## Geometry Proof - DeltaMath

### Problem Statement

**Given:** $ BC \cong AD $ and $ BC \parallel AD $.

**Prove:** $ \triangle BEC \cong \triangle DEA $.

### Proof Structure

| Step | Statement | Reason |
|------|-----------------|--------|
| 1 | $ BC \cong AD $ and $ BC \parallel AD $ | Given |

### Diagram Explanation

The diagram shows a quadrilateral where:
- $ A, B, C, D $ are the vertices of the quadrilateral.
- $ E $ is the point of intersection of the diagonals $ AC $ and $ BD $.
- $ BC $ and $ AD $ are marked as congruent, denoted by a single tick mark on each.
- $ BC \parallel AD $ is indicated by the parallel lines symbols ($\parallel$).

#### Analysis of the Diagram

Based on the given information, here are some properties we can infer:
- Lines $ BC $ and $ AD $ are both equal in length and parallel.
- By the properties of parallelograms or similar quadrilaterals, we can explore the congruence and relationships between the triangles $ \triangle BEC $ and $ \triangle DEA $.

### Steps for Completing the Proof

1. **Given Information**:
- $ BC \cong AD $ (congruent segments).
- $ BC \parallel AD $ (parallel lines).

2. **By Corresponding Angles**:
This can lead to the triangles having equal angles since parallel lines cut by a transversal create equal corresponding angles.

3. **Side-Angle-Side Postulate (SAS)**:
Use the congruent sides and equal corresponding angles from the given information to establish $ \triangle BEC \cong \triangle DEA $.

Completing these logical steps and filling in the types of statements and justifications will validate the proof that $ \triangle BEC \cong \triangle DEA $.
