Show answer & explanation

Answer: (C) D

Explanation

Statements A, B and C hold for every triangle: the largest angle faces the longest side, an exterior angle equals the sum of the two interior opposite angles, and any two sides together exceed the third. D is Pythagoras' theorem, which holds only for right-angled triangles, so it is the odd statement.
