If j = h and k = m, then which expression represents the value of g?

triangle ACB, point E is on segment AC between points A and C and point D is on segment BC between points B and C, creating segment ED, CE equals h, EA equals j, CD equals k, DB equals m, ED equals g, and AB equals f

 g equals f over 2
 g = 2f
 g equals j over h
 g equals k over m

We are given a geometric problem involving triangle \( ACB \), with certain segment lengths provided. We need to determine which expression correctly represents \( g \), the length of segment \( ED \), in terms of other quantities.

### Key Information:
- Triangle \( ACB \).
- Point \( E \) is on segment \( AC \), and point \( D \) is on segment \( BC \), creating segment \( ED \).
- \( CE = h \), \( EA = j \), \( CD = k \), \( DB = m \), \( ED = g \), and \( AB = f \).
- The conditions \( j = h \) and \( k = m \) are given.

### Analysis:
Since \( E \) and \( D \) are located on the segments \( AC \) and \( BC \), this suggests that triangles or other proportional relationships might be involved. However, without specific details on the proportionality or similarity of triangles, we need to rely on the provided conditions.

Given the condition \( j = h \) and \( k = m \), this implies a form of symmetry or balance between the segments. The question asks us to choose an expression for \( g \) from the following options:

1. \( g = \frac{f}{2} \)
2. \( g = 2f \)
3. \( g = \frac{j}{h} \)
4. \( g = \frac{k}{m} \)

### Evaluation of Options:
- **Option 3: \( g = \frac{j}{h} \)** and **Option 4: \( g = \frac{k}{m} \)**: 
  Both of these expressions simplify to \( g = 1 \) because \( j = h \) and \( k = m \). There’s no indication that \( g \) should equal 1, so these seem unlikely.

- **Option 1: \( g = \frac{f}{2} \)**:
  This suggests that \( g \) is half of the total length \( f \), which could be plausible if \( ED \) is the median of the triangle.

- **Option 2: \( g = 2f \)**:
  This suggests \( g \) is twice the length of \( f \), which seems less likely in this configuration.

### Conclusion:
The most plausible answer is **\( g = \frac{f}{2} \)**, assuming \( ED \) is a segment that bisects \( AB \), or forms a median in the triangle.
