Euclidean geometry is an , meaning every theorem is derived from a few simple, assumed truths called axioms or postulates.

Conversely, if a line divides two sides proportionally, it is parallel to the third side.

Using SAS, ASA, and SSS theorems to prove triangles are identical or proportional.

In $\Delta ABC$, let $D$ be a point on $BC$ such that $AD$ bisects $\angle BAC$. If $\angle BAD = 30^\circ$ and $\angle ACD = 50^\circ$, find the measure of $\angle ABC$.
