Unlock the power of geometry with these three fundamental theorems:
> Pythagoras’ Theorem: The gold standard for right-angled triangles. Solve for any side using a² + b² = c².
> Heron’s Formula: Find the area of any triangle using only its side lengths: no height required!
Area = √[s(s−a)(s−b)(s−c)], where s = (a + b + c)/2 is the semi-perimeter.
> Ceva’s Theorem: A deeper dive into triangle geometry. Three cevians AD, BE, and CF are concurrent if
(BD/DC) × (CE/EA) × (AF/FB) = 1.
