“It reveals itself once you complete the rectangle to find the centre. Because, of course, the diagonal passes through the centre once you inscribe a rectangle inside the circle, because of the symmetry”.Tiling the quadrilaterals Simon has crafted applying the inscribed angle theorem.Tiling the “shapes generated by the inscribed angle theorem”“The theorem says that if you have a circle and just three random points on it, then you draw a path between te first point to the second, to the centre, to the third point and back to the first point”.
