Routine calculations is things like doing basic arithmetic not constructing series of pythagorean triples The series of triples can be sourced but the geometric relationship between them can not and is original research Images don t need sourcing but any text accompanying them does and these would need text to explain as they are far from clear and straightforward These are not about the theorem except in the loosest sense containing many instances of the theorem but we already have lots of much clearer pictures of the theorem Finally they are just badly drawn you can make out the numbers in the far too big diagrams above but at the size they d appear in the article as right they re unreadable Not easily fixable as if all the numbers letters and subscripts were of a readable size they d hardly fit on
