  1. 1.6 Polygons Identify and name polygons Find perimeter of polygons

  2. Polygon • A closed figure formed by a finite number of coplanar segments such that • The sides that have a common endpoint are noncollinear • each side intersects exactly 2 other sides but only at their endpoints. B A D C

  3. Convex Polygons • If you draw the lines containing each side none of the lines will contain a point on the interior of the polygon

  4. Concave Polygons • If you draw the lines containing each side, some of the lines pass through the interior of the polygon

  5. A convex polygon in which all sides are congruent is a regular polygon Classifying polynomials

  6. Perimeter • The sum of the lengths of all sides • On the coordinate plane use the distance formula to find the length of the sides P = 2L + 2w w b a L c P = 4s P = a + b + c s

  7. Example: You need to fence in the yard shown in the diagram. How many feet of fencing should you order? If fencing costs $2.28 a foot, how much will you have to spend on fencing material?

  8. Find the perimeter of the figure
