6.1 Polygons6.2 Properties of Parallelograms

Essential Question: How would you describe a polygon?


Polygons

  • 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.


Polygons are named by the number of sides they have:


Describing Polygons

  • 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.


Interior Angles of a Quadrilateral

  • Angles of a quadrilateral add up to 360°.

*problems 14-16 from overhead


Assignment

  • P.325 #4-20, 24-26, 37-39, 41-45


6.2 Parallelograms

  • Parallelogram- quadrilateral with both pairs of opposite sides parallel


4 Properties of Parallelograms

  • 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.


Examples: Using Properties of Parallelograms:
