Across
  1. 3. Exactly equal in size and shape.the sides or segments have the exact same length. its angles have the exact same measure.
  2. 4. A flat surface that can extend forever in length and width but has no thickness. The surface of a calm sea and a flat valley are all physical models of a plane.
  3. 6. An assertion that can be proved true using the rules of logic.it is proven from axioms, postulates, or other ______ already known to be true.
  4. 7. A space figure with two parallel polygonal bases that are the same shape and the same size.
  5. 9. The point on a line segment that divides the given line segment into two congruent parts.
  6. 12. An angle that measures 90° or /2 radians. It is the angle between two perpendicular lines such as the corner of a square or two perpendicular planes such as the wall and the ground.
  7. 13. Points or lines that all lie in the same plane.
  8. 17. A complete circular arc. it also means the distance around the the outside of a circle.
  9. 18. A line segment where two faces of a polyhedron meet.
  10. 20. A pair of angles that add up to 90°.
  11. 22. An angle that has measure more than 90° and less than 180°.
  12. 25. A unit of measure used to measure the magnitude of an angle, equal in magnitude to 1/360 of a complete revolution.
  13. 27. A line segment between two points on the circle or sphere which passes through the center.
  14. 28. Two angles in a plane which share a common vertex and a common side but do not overlap.
  15. 31. A corner point of a geometric figure. For a polygon, vertices are where adjacent sides meet. For an angle, it is where the two rays making up the angle meet.
  16. 32. A three dimensional figure with a single base tapering to an apex. The base can be any simple closed curve.
  17. 33. Also called non-coplanar lines. They are straight lines that are neither parallel, nor intersecting. They lie in different planes.
  18. 35. A closed plane figure bounded by at least three line segments.
  19. 36. are the angles opposite each other when two lines cross
  20. 38. A geometric object that has no dimension and is used to indicate a location.
  21. 39. Two angles that add up to 180°.
  22. 41. The geometric figure formed by two points. it is a straight path connecting two points and extending beyond the points in both directions.
  23. 43. A closed plane figure bounded by at least three line segments.
  24. 44. A pair of numbers that describe the position of a point on a coordinate plane by using the horizontal and vertical distances from the two reference axes.
  25. 45. Two angles that are adjacent (share a leg) and supplementary (add up to 180°)
  26. 46. If the denominator of a fraction is 0
Down
  1. 1. Lying on the same line.
  2. 2. A space figure with two parallel polygonal bases that are the same shape and the same size.
  3. 5. The length of the boundary around a shape or a figure.
  4. 7. two lines that are equal length that never cross
  5. 8. An additional geometric figure that is constructed to assist in solving a problem or producing a proof.
  6. 10. two rays with a common endpoint that point in opposite directions and form a straight line.
  7. 11. An angle that has measure less than 90°.
  8. 14. The distance from the center of a circle to any point on its circumference.
  9. 15. Intuitively speaking, curved away from the eye. the figure is a set of points some of whose chords include points that are in the set.
  10. 16. angles opposite one another at the intersection of two lines. ______ angles are congruent.
  11. 19. The side of a right triangle opposite the right angle. Note: it is the longest side of a right triangle.
  12. 21. All points between two given points (including the given points themselves).
  13. 23. A line segment, line, or plane that divides a geometric figure into two congruent halves.
  14. 24. A perfect round ball. A sphere is a closed solid bounded by a surface on which all points are equidistant from a central point called the center.
  15. 26. A polyhedron whose one face is a polygon and the other faces are triangles with one common vertex. This polygon is the base of the it. The other triangles are the lateral faces. The common vertex of these lateral faces is the vertex of the it. The segment from the vertex perpendicular to the base is called the altitude of the it. The length of the altitude is called the height of the it. The intersections of the adjacent lateral faces are called the lateral edges of it
  16. 29. Intuitively speaking, curved outward or toward the eye.it is curve is a set of points any of whose chords do not include any point that is not in the set.
  17. 30. Two rays sharing a common endpoint. it is typically measured in degrees or radians.
  18. 34. A statement accepted as true without proof. A postulate should be so simple and direct that it seems to be unquestionably true.
  19. 37. Two lines that intersect at right angles.
  20. 40. The surface included within a closed figure, measured by the number of square units needed to cover the surface.
  21. 42. A three-dimensional geometric figure with parallel congruent bases. The bases can be shaped like any closed plane figure (not necessarily a circle) and must be oriented identically.
  22. 47. A planar surface of a solid figure.
