We are given a triangle setup and asked to find the shaded area of triangle \( \triangle BCE \) based on the following information:

- Point \( B \) is halfway between \( A \) and \( C \).
- The distances from \( C \) to \( D \), \( D \) to \( E \), and \( E \) to \( F \) are equal.
- The area of triangle \( \triangle ACF \) is \( 180 \, \text{cm}^2 \).

### Step-by-step approach:

1. **Area of \( \triangle ACF \):**
   The area of triangle \( ACF \) is given as \( 180 \, \text{cm}^2 \).

2. **Relationship between points:**
   - Since \( B \) is halfway between \( A \) and \( C \), this suggests that \( AB = BC \). 
   - \( C \to D \), \( D \to E \), and \( E \to F \) are equal distances, meaning that the line segment \( CF \) is divided into three equal parts.

3. **Proportions of triangles:**
   The key observation here is that since the distances between \( C \), \( D \), \( E \), and \( F \) are equal, and the triangles share a common height (the perpendicular from \( F \) to line \( AC \)), the areas of triangles formed between them will be proportional to their bases.

4. **Find the area of \( \triangle BCE \):**
   \( \triangle BCE \) shares a portion of the base \( BC \) (half of \( AC \)) and its height goes from \( E \) to line \( BC \). Since \( CE \) is two-thirds of the length of \( CF \) (because \( CE \) includes segments \( CD \) and \( DE \)), the area of \( \triangle BCE \) will be a certain fraction of \( \triangle ACF \).

   Since \( CF \) is divided into three equal parts, the ratio of the area of \( \triangle BCE \) to \( \triangle ACF \) is \( \frac{2}{3} \times \frac{1}{2} = \frac{1}{3} \).

   Therefore, the area of \( \triangle BCE \) is:
   \[
   \text{Area of } \triangle BCE = \frac{1}{3} \times 180 = 60 \, \text{cm}^2
   \]

Thus, the shaded area of triangle \( \triangle BCE \) is \( 60 \, \text{cm}^2 \).

Point B is halfway between A and C. The distance from C to D is the same as the distance from D to E, which is the same as the distance from E to F. The area of triangle ACF is 180 cm². How many square centimeters is the shaded area of triangle BCE?

This problem involves finding the shaded area of triangle BCE, using given proportions and the area of triangle ACF (180 cm²). Understand how to use proportions of triangle areas based on equal divisions and shared heights. Suitable for students in Grades 9-12.
