Sorry to anyone who may get annoyed, but what exactly does [ABC] mean, in geometry questions?

\([PQRSTU]\) denotes the area of the polygon \(PQRSTU\). So \([ABC]\) is simply the area of \(\triangle ABC\).

I believe I stated that "\([PQRS]\) denotes the area of figure \(PQRS\)". If you see a question where this detail is not stated, please let me know. Calvin Lin Staff · 2 years, 10 months ago
