Read each question carefully and determine the shape of the cross-section formed when a 3D figure is sliced as described. Draw the cross-section if requested.
1. What is the shape of the cross-section when a rectangular prism is sliced parallel to its base?
Triangle
Rectangle
Circle
Pentagon
2. A cylinder is sliced perpendicular to its base. What shape is the cross-section?
Circle
Square
Rectangle
Ellipse
3. When a cone is sliced parallel to its base, the cross-section is a .
4. A slice through the center of a sphere will always result in a .
5. Describe how you could slice a cube to create a triangular cross-section.
6. It is possible to get a hexagonal cross-section from a cube.
True
