Across
  1. 4. Point B is between points A and C if it is on the line segment connecting A and C.
  2. 11. angles: Two angles in a plane which share a common vertex and a common side but do not overlap. Angles 1 and 2 below are adjacent angles.
  3. 12. Two rays sharing a common endpoint. Angles are typically measured in degrees or radious.
  4. 13. A precise location or place on a plane. Usually represented by a dot.
  5. 15. A pair or set.
  6. 16. distance around the edge of a figure or shape. For example it is the sum of the lengths of each side of polygon. For circles and ellipses, it is called the circumference:
  7. 17. The outer boundary.
  8. 18. Lying on the same line.
  9. 20. Two angles that add up to 180°
  10. 22. any geometric solid that is composed of flat surfaces, each flat surface is called a face.
  11. 24. Evidence establishing a truth or fact.
  12. 25. The highest point of something.
  13. 29. all edges "point outwards"
  14. 30. A solid with flat faces.
  15. 31. Having an oblique direction or position; slanting.
  16. 32. Transparent solid body having triangular shape.
  17. 35. Any straight line that passes through the center of the circle.
  18. 36. A round body whose surface is at all points equidistant from the center. Equation: x 2 + y 2 + z 2 = r 2
  19. 37. A flat surface that is infinitely large and with zero thickness.
  20. 38. A portion of a line which starts at a point and goes off in a particular direction to infinity.
  21. 39. A proposition that requires no proof.
  22. 40. a theoretical proposition, statement, or formula.
  23. 42. A line from the center of a circle to a point on the circle.
  24. 43. The distance around the edge of a figure or shape. For example it is the sum of the lengths of each side of polygon For circles and ellipses, it is called the circumference
  25. 44. line segment where two such surfaces meet.
  26. 45. Dimensional shape with a base.

  4. 5. angle: An angle whose measure is exactly 90°
  5. 6. A geometrical object that is straight, infinitely long and infinitely thin.
  6. 7. Two angles that are adjacent and supplementary.
  7. 8. any of the magnitudes that serve to define the position of a point,line, or the like, by reference to a fixed figure.
  8. 9. A geometrical object that is straight, infinitely long and infinitely thin
  9. 10. Two rays with a common endpoint that point in opposite directions and form a straightline.
