1.  Understand what is meant by:  inverse, implication, conjecture, converse, contrapositive

2.  Given a quadrilateral with vertices A(0,0), B(6,0), C(5,3) and D(1,3), be able to prove that it is an isosceles trapezoid.

            - Prove that BC and AD are congruent

            - Show that the slopes of AB and CD are equal, and, thus, parallel.

3.  Understand  the difference between “exactly one” and “at least one”.

4.  Know how to find the measure of each interior angle and each exterior angle of a regular pentagon and octagon.

5.  Know how the formula for finding the sum of the interior angles of a polygon can be derived.

6.  Know how to use the properties of chords, arcs, and tangents to find missing angles.

7.  Know how to calculate the area of a circumscribed polygon.

8.  Know what is meant by faces, edges, and vertices of a polyhedron.
