How the ellipse is formed?

• Formed if the plane is parallel to the base of the cone

• Formed if the plane is parallel to the slanting height of the cone

• Formed when the titled plane intersects only one cone to form a bounded curve.

• Formed when the plane intersects both nappes to form unbounded curve.

Which of the following define major axis of an ellipse?

• The midpoint of the 2 focus

• The longest diameter of the ellipse

• The shortest diameter of the ellipse

• It is the point where ellipse intersects the major axis

Which of the following define vertices?

• The two extreme points that form the major axis.

• It is formed when the straight plane intersects a right circular cone at an angle greater than zero degrees.

• It is the point where the ellipse intersects the minor axis.

• It is the distance between the end co-vertices.

Which of the following define co-vertices?

• It is formed when the straight plane intersects a right circular cone at an angle greater than zero degrees.

• The two extreme points that form the major axis.

• It is the point where the ellipse intersects the minor axis.

Which of the following define minor axis?

• It is the distance between the end co-vertices.

• It is the distance between the end vertices.

• It always lies on the major axis.

• It is the midpoint between the 2 focus.
