**Introduction
to Conic Sections**

In this lesson an overview of how the different
conic sections can be identified will be the starting point. The picture below shows how the sections are
made by slicing the cones with a plane.
If the software is available, graphing calculator can be used to show
this using technology. A flashlight
demonstration could be used if the technology is not available.

**Formula
Review:**

Distance
formula - _{}

Midpoint formula - _{}

**Identifying Conics by Formula and
Graph**

By identifying the degree of each of
the variables, the leading coefficient of the variables,

and the sign of these leading coefficients, students will
identify the conic section

being expressed.
Practice graphing and identifying conics by opening GSP and graphing

the following:

**Constructing Circles in the Coordinate
Plane**

** **Given the coordinates, segments,
points, or combinations of these, students will be able

to construct circles.
