9/7 1020My measurements and predictions with the various rulers were as follows:
cm_f ruler
sides: 6.25 and 6
hypotenuse predicted/actual: 8.8/8.8
cm_s ruler:
sides: 9.71 and 9.59
hypotenuse predicted/actual: 13.6/13.59
cm_d ruler:
sides: 14.92 and 14.7
hypotenuse predicted/actual: 20.95/21
cm_t ruler
sides: 23.15 and 22.8
hypotenuse predicted/actual: 32.5/32.5
In any given measuring exercise, I would expect the ruler with the smallest determinable increments of measurement to be the most precise. For instance, a ruler with hash marks every .5 cm will be easier to ""read"" than a ruler with hash marks every .1 cm, but the ruler with more hash marks will give a more precise measurement."

That's true until they start blurring together, due to limitations of either eyesight or copier.
