I've seen multiple prep books that tell you that most SAT figures are actually drawn to scale. Is this true? Or is this more of a once-in-a-blue-moon kind of thing? Reply

The only reason some harder problems have figures not drawn to scale is to trap people who will guess. As long as you know how to solve the problem it doesn't make a difference. Reply

The reason why some pictures aren't drawn to scale is to make the problem harder by withholding that "visual cue" that you get from seeing things drawn to scale. If a problem calls for a special right triangle theorem but you don't see the shape of a right triangle it's a harder problem than one that shows you that shape. Reply

I have only taken the SATI twice before and have never tried to bring them with me, so I'm honestly clueless about this. @Godfatherbob: Thanks for the info. Reply

Those questions usually ask for an angle measure or side length, which is necessary to redraw the figure. By the time you have enough information to redraw the picture you will be able to solve the problem. Reply

Watch for problems where the question states a triangle is equilateral, but the figure shows a tall isosceles triangle. Reply
