axis making equal angles with the original three coordinate axes.

Since the coordinate system is rectangular, we have the matrix
[ x ]
[ y ]

The transformation matrix is
[ cos 120   sin 120 ] [ x ] = [ x' ]
[ -sin 120  cos 120 ] [ y ] = [ y' ]<span />

Describe the cross section.
MatroZZZ [7]

Answer: D. Square

The cross section is shown as the shaded region. There are four sides to the shaded figure, so the cross section is a quadrilateral. This rules out choice C. We can also cross choice B off the list because cross sections of 3D figures are 2 dimensional.

Choice A is ruled out as well because we have both pairs of opposite sides that are parallel. The only thing left is choice D. This is true assuming we have a square prism. Any cube is a square prism that has its height equal to the width and length.
