The cross section that results, is a triangle.
Step-by-step explanation:
Cross section is a shape that forms when a slice or a cut is made through a solid.
A solid can have multiple cross sections depending on where you slice the solid.
Cross section perpendicular to the base of a solid will result in triangles.Cross sections parallel to the base of the solid will result in hexagons and so on.
Cross section help in representing three dimension objects in a two dimension way.
