Across
  1. 2. angle An angle with a measure between 0° and 90°.
  2. 3. A solid figure with one face a polygon (the base) and the other faces being triangles that all share the same vertex.
  3. 5. rays Rays that are opposing one another
  4. 7. Side by side
  5. 10. A 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.
  6. 13. The total sum of angles added together to equal 90 degrees
  7. 15. 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.
  8. 16. pair A pair that is linear
  9. 17. An additional geometric figure that is constructed to assist in solving a problem or producing a proof.
  10. 20. A Shape
  11. 21. An ordered pair
  12. 24. Lying on the same straight line.
  13. 25. A unit of measure used to measure the magnitude of an angle, equal in magnitude to 1/360 of a complete revolution.
  14. 28. Two angles that add up to 180°.
  15. 30. angles The pair of angles opposite each other formed by two intersecting lines.
  16. 32. In plane geometry, when one figure fits exactly on top of the other through simple translation and/or rotation, then these two figures are congruent.
  17. 33. angles Two angles that share the same vertex and have one side in common between them.
  18. 34. A straight line or a plane that divides a line, a plane, an angle, or a shape into two equal parts.
  19. 36. The point on a line segment that divides the given line segment into two congruent parts.
  20. 38. They are straight lines that are neither parallel, nor intersecting.
  21. 39. polygon When at least one of the interior angles of a polygon is greater than 180°, it is a concave polygon.
  22. 41. A point is a location in space
  23. 42. A planar surface of a solid figure.
Down
  1. 1. Half of the diameter of a circle
  2. 3. An 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.
  3. 4. 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. 6. polygon The outside of a circle or an ellipse is the convex side; so is the outer surface of a sphere.
  5. 8. A 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.
  6. 9. Points or lines that all lie in the same plane.
  7. 10. Two lines that intersect at right angles.
  8. 11. angle 90 degree angle
  9. 12. segment Part of a line between two points called endpoints.
  10. 13. The boundary, or length of the boundary, that encloses a curved plane figure, usually a circle.
  11. 14. A polyhedron with two parallel, congruent polygons being its bases and all the other faces being parallelograms.
  12. 18. 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.
  13. 19. Also called half-line. It is a straight line that extends from a point.
  14. 20. The length of the boundary around a shape or a figure.
  15. 22. A straight line along which two faces of a solid meet. A rectangular solid has twelve edges.
  16. 23. angle An angle that is between 90° and 180°.
  17. 26. The longest side opposite the right angle in a right triangle.
  18. 27. A point at which the two rays of an angle meet or the intersection point of two sides of a plane figure.
  19. 29. term Term that has not yet been defined
  20. 31. The surface included within a closed figure, measured by the number of square units needed to cover the surface.
  21. 34. Having one thing on either side of it. 2 is between 1 and 3.
  22. 35. A general conclusion proposed to be proved upon the basis of certain given hypotheses or assumptions; or, a general conclusion that has been proved.
  23. 37. 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.
  24. 40. Often referred to as the right cone. A cone is a solid formed by rotating a right triangle around one of its legs.
  25. 41. A set of logical arguments used to deduce or prove a mathematical theorem from a set of axioms.
