  1. 1. The distance from the center of a circle to any point on its circumference.
  2. 5. Often referred to as the right cone. A cone is a solid formed by rotating a right triangle around one of its legs.
  3. 6. 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.
  4. 8. A straight line or a plane that divides a line, a plane, an angle, or a shape into two equal parts.
  5. 9. Another name for analytical geometry.
  6. 11. The side opposite the right angle in a right triangle.
  7. 13. Two or more straight coplanar lines that do not intersect.
  8. 14. A solid bounded by at least four polygonal faces. The pairs of faces meet along their edges. Three or more edges meet in each vertex. A diagonal of a polyhedron is a line segment joining two vertices that are not in the same face.
  9. 18. A straight line or a plane that divides a line, a plane, an angle, or a shape into two equal parts.
  10. 19. A straight line or a plane that divides a line, a plane, an angle, or a shape into two equal parts.
  11. 21. Also called half-line. It is a straight line that extends from a point.
  12. 22. A unit of measure used to measure the magnitude of an angle, equal in magnitude to 1/360 of a complete revolution.
  13. 23. An angle that is between 90° and 180°.
  14. 25. pair of adjacent angles that form a straight line.
  15. 27. A pair of angles that add up to 90°. As shown, 1 is the complementary angle of 2.
  16. 29. Part of a line between two points called endpoints.
  17. 30. A space figure with two parallel polygonal bases that are the same shape and the same size.
  18. 31. the figure formed by two rays from the same initial point .
  19. 32. Intuitively speaking, curved away from the eye. A concave figure is a set of points some of whose chords include points that are in the set.
  20. 37. Two angles that add up to 180°.
  21. 39. The path of a point moving in opposite directions infinitely. A line has neither width nor thickness but length. It is the shortest distance between two points.
  22. 41. A geometric object that has no dimension and is used to indicate a location.
  23. 42. 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.
  24. 43. A general conclusion proposed to be proved upon the basis of certain given hypotheses or assumptions; or, a general conclusion that has been proved, e.g., Pythagorean Theorem, Binomial Theorem, Fundamental Theorem of Algebra, etc.
  25. 45. Often referred to as the right cone. A cone is a solid formed by rotating a right triangle around one of its legs.
  26. 46. A line segment where two faces of a polyhedron meet.
  27. 47. 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.
  28. 48. Also called non-coplanar lines. They are straight lines that are neither parallel, nor intersecting. They lie in different planes.

  1. 2. A line segment that passes through the center of a circle and has its two endpoints on the circle. It also represents the length of such a line segment
  2. 3. A planar surface of a solid figure.
  3. 4. A point B that lies on the line connecting two points A and C and has one of the two points on each side of it. The point B is said to be between points A and C if, and only if, AB + BC = AC, in which AB is the distance from A to B, BC is the distance from B to C, and AC is the distance from A to C.

  17. 35. 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 pyramid. The other triangles are the lateral faces. The common vertex of these lateral faces is the vertex of the pyramid. The segment from the vertex perpendicular to the base is called the altitude of the pyramid. The length of the altitude is called the height of the pyramid. The intersections of the adjacent lateral faces are called the lateral edges of the pyramid.
