Tie Two together:
A & B are both measuring using whole-inch marks
C & D are both measuring using fractional-inch marks
A & D are unbroken rulers
B & C are broken rulers

Thread for Three:
A, B, & C have a rectangle that measures 3 inches
B, C, & D don’t start measuring at the 0” mark on the ruler

Fit All Four:
All four have a rectangle that measures a whole-inch length
All of the rulers still work to measure
All of the rectangles measure an odd-number length
