Study Guide (6.1-6.3)
* Detemine if a figure is a polygon, if so name it according to
its sides, state if its convex/concave, and if its regular or
irregular.
* Know the Polygon Angle Sum Theorem and use it to find
interior angle measure of a polygon.
* Know the Polygon Exterior Angle Sum Theorem and use it to
find exterior angle measures of a regular polygon.
* Given a parallelogram and expressions for angles and sides,
write appropriate equations to find the values of the variables.
* Do a proof with a parallelogram.
* Given 4 vertices, show a figure is a parallelogram
* Given a quadrilateral and expressions for diagonals, find the
values of the variables that make the quad. a parallelogram.
