Knowledge: Knowledge is a conscious relationship to sentences or propositions, which legitimately attributes to them truth or falsehood. What is known is true. Conversely, it does not apply that everything that is true is also known. See also knowledge how, propositional knowledge, realism, abilities, competence, truth, facts, situations, language, certainty, beliefs, omniscience, logical knowledge, reliability

Knowledge/Geometry/Mathematics/Thiel: the classical derivation, e.g. of the Thales Theorem, is based on intuition. (Of course not the measurement of things of the body world.) We conclude and even calculate a bit. Of course, this is not an axiomatic procedure.
Where does the insight come from that a certain geometric theorem is correct?
I 276/277
Knowledge/Thiel: knowledge about the sum of angles in the triangle comes from the knowledge that when two parallel lines are intersected by a third line, the resulting Z angles (alternating angles) are equal.
But how do we know that the Z angles are equal? It is shown in a figure. According to the parallel postulate of Euclid. Also counterfactual assumptions, which are refuted.
