WebA Guide to Euclidean Geometry Teaching Approach Geometry is often feared and disliked because of the focus on writing proofs of theorems and solving riders. The focus of the CAPS curriculum is on skills, such as reasoning, generalising, conjecturing, investigating, justifying, proving or disproving, and explaining. As WebGeometrical Proofs A proof consists of a series of arguments, starting from an original assumption and steps to show that a given assertion is true. Euclid assumed a set of axioms and postulates. Then, he systematically showed the truth of a large number of other results based on these axioms and postulates.
