Welcome back ~victor~ — missed you this week.

Here are the calculations for the given geometry problem.

11.1.1: Calculate $\frac{FD}{CF}$

Step 1: Identify parallel lines and relevant triangles. We are given that $AD \parallel EF$ . Since $G$ and $F$ are points on $EF$ , it means $AD \parallel GF$ . Consider $\triangle CAD$ . The line segment $GF$ is parallel to $AD$ .

Step 2: Apply the Basic Proportionality Theorem (Thales's Theorem). Since $GF \parallel AD$ in $\triangle CAD$ , by the Basic Proportionality Theorem, the line $GF$ divides the sides $AC$ and $CD$ proportionally.
