6.1 Polygons6.2 Properties of Parallelograms

Essential Question: How would you describe a polygon?

- Plane figure formed by three or more sides.
- Each endpoint of a side is a vertex.
- To name a polygon, list its vertices in order.

- Convex
- Concave; (Hint: side is caved in)

- Equilateral
- Equiangular
- Regular – all angles and sides are the same.

*do #1-13 from overhead

- Diagonal – segment that joins two vertices.

- Angles of a quadrilateral add up to 360°.

*problems 14-16 from overhead

- P.325 #4-20, 24-26, 37-39, 41-45

- Parallelogram- quadrilateral with both pairs of opposite sides parallel

- If a quadrilateral is a parallelogram, then its opposite sides are congruent.

- If a quadrilateral is a parallelogram, then its opposite angles are congruent.

- If a quadrilateral is a parallelogram, then its consecutive angles are supplementary.

- If a quadrilateral is a parallelogram, then its diagonals bisect each other.

- Complete #1-21 from overhead
- P. 333 #2-37 depending on time
