Cross Sections

Question 1 • Math 7 B (M12 25/26 S2)

Which of these geometric figures can intersect to form a cross section? Check all that apply.

Answer
A
a line and a prism
B
a line and a rectangle
C
a point and a prism
D
a prism and a horizontal plane
E
a vertical plane and a pyramid

Explanation

A cross section is the two-dimensional shape formed when a plane cuts through a three-dimensional solid. A horizontal plane can intersect a prism, and a vertical plane can intersect a pyramid, so D and E qualify. A line or a point intersecting a solid or a rectangle does not form a cross section.
