Cross Sections of 3D Figures Notes
Today’s Goal – To identify the 2D shape that results from slicing a 3D shape by a plane.
Vocabulary: A ____________ ____________ is the two-dimensional view/shape that is created when a slice is made
through a solid three-dimensional figure.
In the drawing to the right, a square prism is
sliced by a plane that is parallel to its base. The
shape of the cross section it creates is a
__________.
Example 1: If the square prism shown above is sliced perpendicular to its base, what will the shape of the cross section
be?
Example 2: Describe the shape of the cross section of the plane with the cone.
