Normal Equations in Square Geometry

This lecture explores the concept of normal equations in square geometry, using the example of a square ABCD of side length 2. It covers the perspectives from points C and A, discussing the equations and properties of the normal lines. The lecture delves into the locus of points M such as CM'. AC = 0 and CM. AC = -4, illustrating the geometric relationships in the context of normal lines and their intersections.
