Common Mistakes
⚠️
Mistake: Confusing ∠ (angle) with ⟨ (left angle bracket)
Fix: Use ∠ (∠) for geometric angles. The angle brackets ⟨⟩ (⟨ ⟩) are used for bra-ket notation and vectors.
⚠️
Mistake: Using < instead of ∠ for angle notation
Fix: In geometry, use ∠ABC not <ABC for angle notation. The less-than sign < is a comparison operator, not an angle symbol.
