Across

  3. 7. line segment that dive's into two equal halves
  4. 8. an angle that lies outside the polygon
  5. 9. A angle that's 180 degrees
  6. 11. 360 degrees
  7. 14. a line that passes through 2 lines
  8. 17. when an object appear the same after being rotated by 360/n degrees
  9. 21. a angle that sum to 180 degrees but are not equivelent

Down
