Spiralaterals with 2 numbers will make a rectangle or a parallelogram. Any set of numbers that is a repetition of one number (I.e. 1,1,1,1,1,1,1,1. 7,7,7,7,7,7,7. e.t.c) will also make rectangles. Also numbers that repeat two of the numbers but not the third one (I.e. 1,1,1,2,2,2,4. 3,3,3,3,3,1,5,5,5,5.)will make rectangles that will just go off and not return to their starting point.…
