  1. 1. GT GeometryPut CW/HW from yesterday on the corner of your desk, with a pen.
  2. 2. Geom Drill 4/9/13 2x-3Find thelength of the 5xlonger ofthe twoparallel 7X+5sides.
  3. 3. REGULAR POLYGONDescribe perimeter s1 s s8 2 s7 s3 s6 s5 s4
  4. 4. REGULAR POLYGONWrite a formula for the area s1 s s8 2 a s7 s3 s6 s5 s4
  5. 5. Find the area of the regular hexagon using formulasyou already know. Important information: RegularHexagon, OA is the radius of the circumscribed circle FA AB BC CD DE EF
  6. 6. OBJECTIVETO STATE AND APPLY THE FORMULA FOR THE AREA OF AREGULAR POLYGON.
  7. 7. REGULAR POLYGONAll angles congruent and all sides congruent.
  8. 8. VocabularyCenter of a regular polygon is center of the circumscribed circle.
  9. 9. VocabularyRadius of a regular polygon is distance from the center to a vertex.
  10. 10. VocabularyCentral angle of a regular polygon is the angle formed by two radii drawn to consecutive vertices.
  11. 11. vocabularyApothem of a regular polygon is the shortest distance from the center of the polygon to a side.
  12. 12. AREA OF A REGULAR POLYGONA = 1/2(ap)a: apothemp:perimeter of the polygon
  13. 13. FIND THE AREA:(exact)Apothem is 9, figure is regular
  14. 14. FIND THE AREA: (exact)Radius is 4, figure is regular
  15. 15. FIND THE AREA:Side is 4, figure is regular
