Across
  1. 3. are 360 degrees in one Full Rotation (one
  2. 8. point where two or morestraight lines meet A corner
  3. 10. acute angles that add up to 90°. For example, 40° and 50° are complementary. In the diagram below, angles 1 and 2 are complementary.
  4. 11. three dimensional figure with a single base tapering to an apex. The base can be any simple closed curve. Often the word cone refers to a right circular cone.
  5. 13. distance from the center to the edge of a circle
  6. 17. in both directions without end (infinitely).
  7. 18. sides are triangles which meet at the top (the apex)
  8. 20. is a very special idea We know we can't reach it but we can still try towork out the value of functions that have infinity in them
  9. 23. no thickness, and
  10. 24. one of the most basic curvilinear geometric shapes, the surfaceformed by the points at a fixed distance from a given line segment, the axis of the cylinder.
  11. 25. is half of the circle's diameter
  12. 26. geometric proof involves writing reasoned, logical explanations that use definitions, axioms, postulates, and previously proved theorems to arrive at a conclusion about a geometric statement
  13. 27. are parallel if they are always the same distance apart (called "equidistant") and will never meet (They also point in the same direction)
  14. 29. base is a polygon (a straight-sided shape)
  15. 32. segmentPart of a line connecting two points
  16. 33. equal in size and shape. Congruent sides or segments have the exact same length. Congruent angles have the exact same measure. For any set of congruent geometric figures, corresponding sides, angles, faces, etc. are congruent.
  17. 35. solid object that has two identical ends and all flat sides.
  18. 36. Angles are Supplementary if they add up to 180 degrees
  19. 39. goes to infinity)
  20. 40. a proposition that requires no proof beingselfevident or that is for a specific purpose assumed true andthat is used in the proof of other propositions axiom
  21. 41. angleA right angle is an internal angle which is equal to 90°
  22. 42. in this case means they share the same Vertex (corner point) not the usualmeaning of up-down
  23. 44. polygon-A polygon that has all interior angles less than 180°
  24. 46. rays sharing a common endpoint. Angles are typically measured in degrees or radians.
  25. 47. angleVertical" in this case means they share the same Vertex (or corner point), not the usual meaning of up-down
  26. 50. just means at right angles (90°) to
  27. 52. world has three dimensions, but there are only two dimensions on a plane.
  28. 53. point on the surface is the same distance from the center
  29. 54. circle around).
  30. 55. line segment, line, or plane that divides a geometric figure into two congruent halves.
  31. 56. of the individual surfaces of a solid object
Down
  1. 1. is the distance around a two-dimensional shape
  2. 2. All the vertices point 'outwards', away from the center.)
  3. 4. pair of adjacent angles formed by intersecting lines. Angles 1 and 2 below are linar linearpair So are angles 2 and 4, angles 3 and 4, and angles 1 and 3 Linear pairs of angles are supplementary
  4. 5. can be "skewed" meaning it tends to have a long tail on one side or the other
  5. 6. B is between points A and C if it is on the line segment connecting A and C.
  6. 7. polygonA polygon that has one or more interior angles greater than 180°
  7. 9. point is an exact location It has no size only position
  8. 12. in Geometry means to draw shapes, angles or lines accurately.
  9. 14. angle that has measure more than 90° and less than 180°
  10. 15. plane shape (two-dimensional) with straight sides
  11. 16. angleAn angle that has measure less than 90°.
  12. 19. line with a start point but no end point
  13. 21. on the same line.
  14. 22. a right angled triangle:
  15. 23. side opposite the right angle in a right-angled triangle
  16. 28. moving points "A" and "B"
  17. 30. straight line going through the center of acircle connecting two points on the circumference.
  18. 31. the rays below by dragging any orange dot. The two rays (blue and red) will only be opposite when they point in exactly opposite directions
  19. 34. edge is a line segment that joins two vertices.
  20. 37. middle of The point halfway along
  21. 38. anglesAn angle that has measure less than 90°.
  22. 43. complete circular arc. Circumference also means the distance around the the outside of a circle.
  23. 45. the coordinate plane, the pair of numbers giving the location of a point (ordered pair). In three-dimensional coordinates, the triple of numbers giving the location of a point (ordered triple). In n-dimensional space, a sequence of n numbers written in parentheses.
  24. 48. the same plane.
  25. 49. 3-dimensional object shaped like a ball
  26. 50. solid with flat faces
