In the proof of Theorem 30, the auxiliary line $CE$ is drawn —

aperpendicular to $BC$
bparallel to $AD$
cequal to $AD$
dparallel to $BC$

ব্যাখ্যা

In proving the Internal Bisector Theorem, the auxiliary line $CE$ is drawn through $C$ parallel to the bisector $AD$ (meeting $BA$ produced at $E$ ). This parallel allows the angle bisection to be transferred and the Basic Proportionality Theorem to be applied.
