Across
  1. 3. the inside of a circle
  2. 5. distance from the center of the polygon to a side of a polygon
  3. 6. a circle that passes through all the vertices of a polygon
  4. 11. all angles and sides are congruent
  5. 13. the amount of space within a shape
  6. 14. you use this when solving a law of sines problem when the variable is on the bottom
  7. 15. a 2 dimensional shape with straight sides
Down
  1. 1. all the sides of shape added together
  2. 2. polygon the largest possible circle that can be drawn inside a circle
  3. 4. you use this when solving a law of sines problem when trying the find an angle of a triangle
  4. 7. you use the law of sines when you see this on a non right triangle
  5. 8. an angle whose vertex is at the center
  6. 9. you use this when solving a law of sines problem when the variable is on the top
  7. 10. the distance from the center to the outside
  8. 12. you use the law of sines when you see this on a non right triangle
