Introduction to Conic Sections

What is formed when the plane intersects the cones at the vertex only?

• Degenerate conics

• a point

• a single line

• intersecting lines

What is formed when the plane intersects tangent to the cones?

• degenerate conics

• a point

• a single line

• intersecting lines

A circle is a special type of an ellipse.

• TRUE

• FALSE
