The cross-section of the cone can not be a rectangular shape.
What is coordinate geometry?
A coordinate plane is a 2D plane which is formed by the intersection of two perpendicular lines known as the x-axis and y-axis.
When a right circular cone is cut then there can be a shape of a triangle or a shape of ellipse or a shape of circle but there will not be a shape of a rectangle.
Therefore the cross-section of the cone can not be a rectangular shape.
