From The Notebooks of Leonardo da Vinci edited by Edward McCurdy
Manuscript G 17 r
When two circles touch the same square at four points, one is double the other.
Manuscript G 17 v
The circle that touches the angles of an equilateral triangle is triple the triangle that touches the sides of the same triangle.
As near as I can tell, the statemtn from G17r is true, but the statement from G17v is not true.
Am I missing something? Is there any way that the statement from G17v can be true?
