Another triangle that you're almost sure to see on your standardized
test is the 30°/60°/90° triangle. Often, you'll see it when
an equilateral triangle is divided into two triangles of equal size. Learn
the side-length ratio for the 30°/60°/90° triangle and you'll
save yourself many calculations on test day.
If we set x as the length of the
shortest side (the side opposite the 30° angle), then the side opposite
the 60° angle has length x √3,
and the hypotenuse has length 2x.
