  1. 10-8 Polygons and Tessellations

  2. polygon • Simple closed figure formed by straight lines

  3. Classified by # of sides! • 5 • 6 • 7 • 8 • 9 • 10

  4. How many degrees are in each polygon? • There is a formula! • (n-2)(180)= • n = the number of sides

  5. Regular polygon • All sides and angles are congruent • They are “equiangular” and “equilateral”

  6. How do we find each angle of a regular polygon? • = this will be what just one angle of a regular polygon. • n= the number of sides

  7. Example! • How many degrees does an angle in a regular hexagon have?

  8. Tessellation • A repetitive pattern of polygons that fit together with no overlaps or holes • How do you know if you can make a tessellation? • The angle measurements Divide evenly into 360

  9. Can you make a tessellation from a regular pentagon?
