How does one write robust Geometric Proofs?
One of the most challenging – and intimidating – aspect of Subtest II: Geometry, is writing Proofs for Geometric Propositions. Kids in schools HATE proofs universally (!), and I must say that teachers do their tuppence to cultivate such sentiments. The allergy of students against Proofs shouldn’t be particularly surprising: many Geometry teachers themselves cower at the sight of an ‘unfamiliar’ Proof! Proofs require you to reason very logically and analytically – the deductive reasoning is of a high order! – and it calls for a peculiarly methodical approach not encountered elsewhere. With regards to the CSET, you’re sure to encounter at least a couple of Proofs in the MCQ section wherein you are expected to supply the missing step of a Proof by selecting the most relevant choice. Likewise, AT LEAST one Q in the Free Response section shall be a Proof. And, obviously, this might be one you’re familiar with, or something novel and challenging. But proofs are actually quite simple once you
