Constructed Response Sample –MGSE.7.G.3
A right cylinder and a right rectangular pyramid are shown.
Part A
Name the 2-dimensional shape that is a cross section of both the cylinder
and the pyramid. Explain how the cross section is obtained.
Part B
Name two 2-dimensional shapes that are cross sections of the cylinder, but
that are not cross sections of the right rectangular pyramid. Explain how
each cross section is obtained.
Part C
Name two 2-dimensional shapes that are cross sections of the right
rectangular pyramid, but that are not cross sections of the cylinder. Explain
how each cross section is obtained.

Exemplar
Part A
A rectangle is a vertical cross section of the cylinder and a horizontal cross
section of the pyramid.
Part B
[Note: Student responds with any two of the following statements.]
A circle is a horizontal cross section.
An oval (ellipse) is an angled cross section.
A parabola (or hill shaped) figure is a cross section from the lateral surface to
the base.
Part C
A triangle is a vertical cross section.
A trapezoid is an angled cross section.
