What is the shape of the cross section of the figure that is perpendicular to the triangular bases and passes through a vertex of
the triangular bases?
x

a parallelogram that is not a rectangle
a rectangle
a triangle that must have the same dimensions as the bases
a triangle that may not have the same dimensions as the bases

B. a rectangle

Step-by-step explanation:

When a figure is sliced along a given or required plane, the cross section of the sliced surface produces another figure or shape.

In the question, the figure has a triangular base. So that, the cross section along the required plane would give a rectangular shape. This is because the cross section is perpendicular to the triangular base, and passes through a vertex of the base.

By appropriate procedures and the given conditions, the shape of the cross section would be a rectangle.
