<p>Unlike the ACT, SAT figures without the “not to scale” label are as accurate as the printing process allows. For example , BB pg. 548 #4 … try measuring the angles with a protractor.</p>
<p>During a test, you could do BB pg. 673 #16 e.g. by making fingernail “scale” marks on your pencil and measuring AD by length … no doubt, math is better, but the pencil ruler can be a useful last resort or sanity check.</p>
