Precalculus Conic Sections

There are _____ types of conic sections.

• 1

• 2

• 3

• 4

• Circle

• Ellipse

• Parabola

• Hyperbola

TRUE or FALSE: A circle is a special type of ellipse.

• TRUE

• FALSE

What type of conic section is shown?

• Ellipse

• Hyperbola

• Parabola

• Circle

What does (h,k) stand for in the standard circle equation?

• (h,k) is the center of the circle

• (h,k) is a point on the circle.

• (h,k) is a point that we guess and find

• (h,k) is the distance of the circle

Write the equation of a circle with center (7, 0) with radius 3.

• (x - 7)² + y² = 9

• x² + (y -7)² = 9

• (x - 7)² + y² = 3

• x² + (y -7)² = 3

The following are degenerate conics except:

• Point

• Pair of intersecting lines

• Plane

• Single Line

If the plane cuts the cone in the similar fashion but at a certain angle, then the conic section is an __________.

These are figures that formed by intersecting two inverted cones and a plane.

• Cross Sections

• Conic Sections

• Circles

• Parabolas
