What is a polygon? Polygons: Not Polygons:

Polygons: Closed figure formed by a finite number of coplanar segments such that: The sides that have a common vertex are not collinear Each side intersects exactly two other sides, but only at their endpoints

Types of Polygons # Sides Name 3 4 5 6 7 8 9 10 11 12 n

Classifying Polygons Convex Concave

Angles and Sides Equilateral Polygons Equiangular Polygons All Sides are congruent All Angles are congruent

Regular Polygons: Have congruent sides and congruent angles

Practice: Draw it A: A regular quadrilateral B: An irregular pentagon C: A concave octagon D: A convex hexagon

Perimeter and Circumference Perimeter-distance around an object How do you calculate it? -Perimeter of a circle??

Calculate the perimeters A square with a side that measures 5in A rectangle with a length of 3m and a width of 9cm. A circle with a radius of length 6m.

Find the perimeter

Find the perimeter of pentagon ABCDE that has the following vertices: A: (0, 4) B: (4,0) C: (3, -4) D: (-3, -4) E: (-3, 1)

The width of a rectangle is 5 less than twice its length The width of a rectangle is 5 less than twice its length. The perimeter is 80cm. Find the dimensions.
