  10. 20. / a plane figure with four equal straight sides and four right angles.
  11. 21. /of a flat, or plane figure is the number of unit squares that can be contained within it. The unit square is usually some standard unit, like a square meter, a square foot, or a square inch.
  12. 22. / a plane figure with four straight sides and four right angles, especially one with unequal adjacent sides, in contrast to a square.
  13. 25. a circle or sphere.
  14. 27. angle/ 180 angle
  15. 28. /of an angle is defined in the context of a right triangle: for the specified angle, it is the ratio of the length of the side that is opposite that angle to (divided by) the length of the longest side of the triangle
