Answer :
Answer:
Ellipse
Step-by-step explanation:
From the given information:
Suppose the plane cuts the cone in such a manner that the plane is neither perpendicular nor parallel to the axis and also the angle of intersection is greater than the generator angle.
Then the conic section formed is an Ellipse.
The Conic Section that is formed from the intersection of the central axis at an angle between 40° and 90° will be An Ellipse.
How to transform a Plane?
Let us consider that the plane cuts the cone in such a manner that the plane is neither perpendicular nor parallel to the axis and also the angle of intersection is greater than the generator angle.
Thus, we can say that when the plane intersects the double-napped cone in such a manner that the angle between the vertex and the angle is greater than the vertex angle.
Then the resulting conic section formed is an Ellipse.
