Geometry Thompson
Across
- 1. Have a common endpoint that form a line.
- 6. A premise or starting point of reasoning.
- 7. A three dimensional solid consisting of all points eduidistant from a given point.
- 10. A line segment,, line, or plane, that divides a geometric figure into two congruent halves.
- 14. Two things that are located or facing directly across.
- 15. Lines in three dimensional space that do not intersect and are not parallel.
- 16. A part of a line starting at a particular point and extending infinitely in one direction.
- 19. A shape or solid which has an indentation or "cave".
- 21. The distance around the outside of a plane figure.
- 22. In a plane which share a common vertex and a common side but do not overlap.
- 24. A pair of adjacent angles formed by intersecting lines.
- 27. Two distinct coplanar angles that do not intersect.
- 28. A line segment where two faces of a polyhedron meet.
- 29. An additional geometric figure that is constructed to assist in solving a problem or producing a proof.
- 30. A complete circular arc. Can also mean the distance around the the outside of a circle.
- 31. At 90°.
- 34. A pair that add up to 90°.
- 37. A flat surface extending in all directions.
- 38. Lying on the same line
- 40. A three-dimensional geometric figure with parallel congruent bases.
- 41. A unit of angle measure equal to of a complete revolution.
- 43. A planar surface of a solid figure.
- 44. The point halfway between two given points.
- 45. Exactly equal in size and shape. Sides or segments have the exact same length. These angles have the exact same measure. For any set of same geometric corresponding sides, angles, faces , etc. are equal.
- 46. Two rays sharing a common endpoint. These are typically measured in degrees or radians.
- 47. A line segment between two points on the circle or sphere which passes through the center.
Down
- 2. At a 90° angle.
- 3. A geometric figure with no indentations. Formally, a geometric figure is this if every line segment connecting interior points is entirely contained within the figure's interior.
- 4. A corner point of a geometric figure.
- 5. A solid with parallel congruent bases which are both polygons. The bases must be oriented identically.
- 8. A polyhedron with a polygonal base and lateral faces that taper to an apex.
- 9. has measure more than 90° and less than 180°.
- 11. A solid with no curved surfaces or edges.
- 12. Having one thing on either side of it
- 13. opposite one another at the intersection of two lines.
- 17. The surface included within a closed figure, measured by the number of square units needed to cover the surface.
- 18. The "slope" of a vertical line.
- 20. The geometric figure formed by two points.
- 23. Two lines that add up to 180°.
- 25. Has a measure of less than 90°.
- 26. A general proposition not self-evident but proved by a chain of reasoning; a truth established by means of accepted truths.
- 27. The geometric figure formed at the intersection of two distinct lines..
- 32. The side of a right triangle opposite the right angle.
- 33. A three dimensional figure, with a single base tapering to an apex. The base can be any simple closed curve.
- 34. the pair of numbers giving the location of a point. (ordered pair).
- 35. All points between two given points (including the given points themselves).
- 36. A closed plane figure for which all sides are line segments.
- 37. Uses definitions, axioms, postulates, and previously proved theorems to arrive at a conclusion about a geometric statement.
- 39. A line segment between the center and a point on the circle or sphere.
- 42. Lying in the same plane. For example, any set of three points in space.
