### Geometric Analysis: Square Properties and Angles

**Given:**

- \( EFGH \) is a square.
- \( GJ = 15 \)
- \( EF = 15\sqrt{2} \)
- \( \angle EFH = 45^\circ \)

**Problem Statement:**

Match each segment or angle to its measure.

**Diagram:**
The given diagram depicts a square \( EFGH \) with a diagonal \( EG \). There is also an internal point \( J \) on the diagonal \( EG \). Segment \( GJ \) is marked as 15.

**Tasks:**
You need to match the following measures with the correct segment or angle:

1. 15
2. 30
3. 45°
4. 90°
5. \( 15\sqrt{2} \)

**Segments and Angles to Match:**

1. \( \overline{EH} \)
2. \( \overline{FJ} \)
3. \( \overline{EG} \)
4. \( \angle HEF \)
5. \( \angle GEF \)

**Detailed Explanation of the Diagram:**

- **EH:** This is a side of the square \( EFGH \).
- **FJ:** A segment from point \( F \) to an internal point \( J \).
- **EG:** Diagonal of the square \( EFGH \).
- **\angle HEF:** An angle at vertex \( E \) between sides \( EH \) and \( EF \).
- **\angle GEF:** An angle at vertex \( E \) between sides \( GE \) and \( EF \).

**Solution Approach:**

1. **\( \overline{EH} = 15 \)**:
   Since \( EH \) is a side of the square and \( EFG \) is a square with \( EF = EH \), and also \( EH = GJ = 15 \).

2. **\( \overline{FJ} = 15 \)**:
   This was marked on the diagram.

3. **\( \overline{EG} = 15\sqrt{2} \)**:
   This is the diagonal of square \( EFGH \). In any square, the diagonal (using Pythagoras theorem) is \( \sqrt{2} \) times the side length.
