The regular hexagon shown above is divided into six congruent equilateral triangles. What
is the measure, in degrees, of one of the interior angles of the hexagon?
A) 60°
B) 120°
C) 180°
D) 360°Here’s How to Crack It
First, you can Ballpark and eliminate (C) and (D); (C) would be a straight line, and (D) is all the way
around a circle, so neither of those can be the interior angle of this figure. Next, label what you know. If
each of the triangles in the figure is equilateral, then all of the angles within the triangles are equal to 60°.
The interior angles of the hexagon are comprised of two angles of the triangles, so the interior angles of
the hexagon must be 2 × 60 = 120°, which is (B).

Trigonometry will likely appear on your SAT. But fear not! Many trigonometry questions you will see
mostly require you to know the basic definitions of the three main trigonometric functions. SOHCAHTOA
is a way to remember the three functions:
