In the exam hall, yaar, forget fancy triangles—just draw two quick ones. For 30-60, sketch half an equilateral triangle with side 2; for 45, draw a right-isosceles with legs 1. Then use Pythagoras to fill the sides and write the ratios.
That's how my sister and I revise at 4 a.m. before she leaves for her college and I collapse into sleep—she quizzes me, and the numbers stick better than any memorised table.
