Pre-Calc Quiz 1 Flashcards
Conic Sections & Circles
3-dimensional shape formed by set of line segments connecting to a common point.
Cone
The common point that the set of line segments of a cone connects at.
Apex or Vertex
Distance from vertex of a cone to its flat base is the _____
Height of the cone
Its ____ is the segment joining the vertex and the center of the circular base.
Axis
Two types of cones
Right Circular Cone and Oblique Cone
Cone which has a circular base and the axis is perpendicular with the base of the cone.
Right Circular Cone
A cone of which the axis is not perpendicular with its base.
Oblique Cone
Geometric figure made up of two right circular cones with a common vertex or apex.
Double Right Circular Cone
Intersection of a plane and a double right circular cone.
Conic Section or Conic
Line lying entirely on the cone.
Generator
Where do all generators of a cone pass through
Vertex
The only point where the two nappes of the DRCC intersect.
Vertex
Two types of conics
Degenerate and Non-Degenerate
A point, a line, or two intersecting line. Formed when a plane intersects DRCC passing the vertex.
Degenerate Conic
This is a conic, either a parabola, an ellipse, or a hyperbola.
Non-Degenerate Conic
