In the given diagram, we need to prove that \( \triangle ADE \) is similar to \( \triangle ABC \) by showing that two pairs of angles are congruent.

### Step-by-step reasoning:
1. **Angle \( \angle DAE \)** is a common angle between both triangles \( \triangle ADE \) and \( \triangle ABC \).
   - So, \( \angle DAE = \angle BAC \).
   
2. Since \( DE \parallel BC \) and \( AB \) is a transversal line, **corresponding angles** are equal:
   - \( \angle ADE = \angle ABC \).

3. By the **AA (Angle-Angle) similarity criterion**, if two corresponding angles are equal, the triangles are similar.
   - Thus, \( \triangle ADE \sim \triangle ABC \).

### Drag and Drop Answer:
- \( \angle DAE = \angle BAC \) (common angle)
- \( \angle ADE = \angle ABC \) (corresponding angles, \( DE \parallel BC \))
- \( \triangle ADE \sim \triangle ABC \) (Two respective angles are equal)
