Answer:
Option (b) is correct.
Triangle is the shape of the cross section.
Step-by-step explanation:
Given : A square pyramid is sliced so that the cross section is perpendicular to its base. The cross section intersects the vertex of the pyramid.
We have to determine the shape of the cross section.
Since, the square pyramid is sliced such that the cross section is perpendicular to its base.
also, The cross section intersects the vertex of the pyramid.
We will obtain a triangle when we slice it such that cross section is perpendicular to its base. (as shown in attachment)
ΔABC is the shape of cross section.
Option (b) is correct.
