Help pls /All vertical and horizontal cross sections of any one cube are all the same size and shape. What about vertical and horizontal cross sections of a pyramid? Are they all the same size? Are they all the same shape?
No, the vertical and horizontal cross sections of a pyramid are not all the same size or shape. The size and shape of the cross sections depend on the location of the cut and the angle of the cut. For example, a horizontal cross section of a pyramid taken at the base will be the same size and shape as the base, while a vertical cross section taken through the apex will be a triangle.
and a vertical section not through the apex, cutting two opposite sides of the base will be a trapezoid
a vertical section cutting two sides of the base will be a triangle.
