  1. 2. angle-An angle that is between 90° and 180°.
  2. 6. ordered pair
  3. 10. planar surface of a solid figure.
  4. 13. total sum of angles added together to equal 90 degrees
  5. 16. A point at which the two rays of an angle meet or the intersection point of two sides of a plane figure.
  6. 18. angles The pair of angles opposite each other formed by two intersecting lines.
  7. 19. Also called half-line. It is a straight line that extends from a point.
  8. 22. additional geometric figure that is constructed to assist in solving a problem or producing a proof.
  9. 25. 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.
  10. 26. 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.
  11. 27. segment-Part of a line between two points called endpoints.
  12. 31. longest side opposite the right angle in a right triangle.
  13. 33. pair-A pair that is linear
  14. 34. straight line or a plane that divides a line, a plane, an angle, or a shape into two equal parts.
  15. 35. polyhedron with two parallel, congruent polygons being its bases and all the other faces being parallelograms.
  16. 38. unit of measure used to measure the magnitude of an angle, equal in magnitude to 1/360 of a complete revolution.
  17. 41. referred to as the right cone. A cone is a solid formed by rotating a right triangle around one of its legs.
  18. 43. surface included within a closed figure, measured by the number of square units needed to cover the surface.
  19. 44. straight line along which two faces of a solid meet. A rectangular solid has twelve edges.
  20. 45. The figure formed by two rays from the same initial point. The two rays are called the sides of the angle and the initial point is called the vertex of the angle.

  1. 1. A set of logical arguments used to deduce or prove a mathematical theorem from a set of axioms.
  2. 3. Two angles that add up to 180°.
  3. 4. point on a line segment that divides the given line segment into two congruent parts.
  4. 5. point is a location in space
  5. 6. on the same straight line.
  6. 7. angles-Two angles that share the same vertex and have one side in common between them.
  7. 8. length of the boundary around a shape or a figure.
  8. 9. lines that intersect at right angles.
  9. 11. angle-An angle with a measure between 0° and 90°.
  10. 12. one thing on either side of it. 2 is between 1 and 3.
  11. 13. boundary, or length of the boundary, that encloses a curved plane figure, usually a circle.
  12. 14. by side
  13. 15. or lines that all lie in the same plane.
  14. 17. Half of the diameter of a circle
  15. 20. rays-Rays that are opposing one another
  16. 21. initial proposition or statement that is generally accepted as true without proof (self-evident truth) and from which further statements, or theorems, can be derived by using logical deduction.
  17. 22. plane geometry, when one figure fits exactly on top of the other through simple translation and/or rotation, then these two figures are congruent.
  18. 23. A general conclusion proposed to be proved upon the basis of certain given hypotheses or assumptions; or, a general conclusion that has been proved.
  19. 24. path of a point moving in opposite directions infinitely. A line has neither width nor thickness but length.
  20. 28. A solid figure with one face a polygon (the base) and the other faces being triangles that all share the same vertex.
  21. 29. tubular solid with a circular base. Usually, this term implies a right cylinder that can be formed by rotating a rectangle about one of its sides.
  22. 30. term Term that has not yet been defined
  23. 32. three-dimensional figure bounded by plane polygonal faces. The point at which three or more faces meet is called a vertex. A line along which two faces meet is called an edge.
  24. 36. 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.
  25. 37. polygon-When at least one of the interior angles of a polygon is greater than 180°, it is a concave polygon.
  26. 39. polygon-The outside of a circle or an ellipse is the convex side; so is the outer surface of a sphere.
