Answer:
Option 1 - Triangle
Step-by-step explanation:
Given : A cone is sliced so the cross section is parallel to its base.
To find : What is the shape of the cross section?
Solution :
When a cone is cut in such a way that the cross-section is perpendicular to the base and it passes through the vertex.
The shape of cross section formed is a triangle.
Refer the attached figure below.
The figure thus formed after cutting is in the shape of a triangle.
Therefore, Option 1 is correct.
