Let’s see a simple example to make it clearer. Let’s say we have 2 standard dice, we roll both and […]

An Insight Into Projective Geometry
Projective Geometry is a very nice tool we can employ when we have to work with a lot of intersections and it can even handle intersections on circles. Now let’s gain an insight into its main principles. Oh Cross Ratio, My Cross Ratio A proof involving projective geometry always (and when I say always I […]
