Respuesta :
The three-dimensional figure that will produce a trapezoid if its cross section was cut by a plane that is not parallel to its base is the rectangular pyramid. If a plane was cut parallel to the base of the pyramid, the shape that would be produced would be a rectangle.
The three-dimensional figure which has a cross section in the shape of a trapezoid if it is sliced by a plane that is parallel to a side other than its base is rectangular pyramid or square pyramid.
What is a trapezoid and rectangular pyramid?
Trapezoid can be defined as a quadrilateral having one pair of its opposite sides parallel. The non-parallel sides are called laterals or legs of the trapezoid.
Rectangular pyramid is a 3 dimensional figure having rectangle as its base and a triangular face corresponding to each side of the base.
Whereas a square pyramid has its base in form of a square.
When a rectangular or square pyramid is cross-sectioned by a plane that is parallel to a side other than its base, the result would be in the shape of a trapezoid.
