Imagine a cross section parallel to a side of the pyramid and moving closer to that side. What happens to the size and shape of the cross section?
Answers
Answer:
A cross section is the shape you see when you make one slice through a solid. A solid can have many different cross sections depending on where you make the slice. Consider the following hexagonal pyramid.
Cross sections perpendicular to the base and through the vertex will be triangles. Below, you can see a plane cutting through the pyramid, part of the pyramid removed, and the cross section.
You could also take a slice parallel to the base. Cross sections parallel to the base will be hexagons.
It is also possible to take cross sections using planes that are neither parallel nor perpendicular to the base. These can be much more difficult to visualize. Physical models or dynamic geometry software are extremely helpful. For example, the same hexagonal pyramid has been sliced at a slant below. The cross section is a pentagon.
Cross sections are one way of representing three dimensional objects in two dimensions.
Answer:
the cross section gets bigger but stays a trapezoid
