Question
**Mathematics: Midsegments in Triangles**

**Problem:**

Consider the diagram shown, representing an 8 inch by 8 inch square air vent. Points A, B, C, D, E, F, and G are labeled in a triangular and linear configuration. The length AG is given as 8 inches. 

Key points to consider:
- \(BF\) is the midsegment of \(\triangle ADG\).
- \(CE\) is the midsegment of \(\triangle DBF\).

**Question:**

What is the measure of \(CE\)?

**Options:**

A. 2 inches  
B. 3 inches  
C. 4 inches  
D. 6 inches  

**Solution Explanation:**

- In \(\triangle ADG\), \(BF\) is the midsegment, so it is half the length of \(AG\).

- Since \(AG = 8\) inches, \(BF = \frac{1}{2} \times 8 = 4\) inches.

- Similarly, in \(\triangle DBF\), \(CE\) is the midsegment. Thus, \(CE\) is half the length of \(BF\).

- Since \(BF = 4\) inches, \(CE = \frac{1}{2} \times 4 = 2\) inches.

So, the measure of \(CE\) is 2 inches.

**Correct Answer:** A. 2 inches
