- 2. A specific position on a line, plane, or in space.
- 4. – points that do not lie on the same plane.
- 6. A closed figure with eight sides.
- 7. – points that lie on the same line.
- 10. A solid or hollow object that tapers from a circular or roughly circular base to a point.
- 11. A flat two-dimensional surface upon which two-dimensional objects (e.g., circle, square) can lie, or the face of a three-dimensional object as it creates a surface (e.g., face of a cube); the dimensions of which are infinite.
- 13. Also known as corner/corners. The point at which two sides of a two-dimensional figure or two edges of a three-dimensional figure meet.
- 15. A special type of rectangle that has equilateral (same length) sides and parallel opposite sides.
- 16. A round body whose surface is at all points equidistant from the center.
- 19. a segment – a point that divides the segment into two congruent segments.
- 20. – angles that have the same measure.
- 23. – angle whose measure is greater than 90 degrees but less than 180 degrees.
- 25. Having a plane-like quality.
- 26. – ray that divides an angle into two congruent adjacent angles.
- 27. Terminology to describe the dimensions of an object or set. With young children, the terms large, medium, small, taller, shorter, longer, less than and greater than are all appropriate.
- 28. – points that do not lie on the same line.
- 31. Two lines that meet to make a corner.
- 32. – angle whose measure is 180 degrees.
- 34. A closed figure with three sides.
- 35. Identical in size and shape.
- 36. – angle whose measure is 90 degrees.
Down
- 1. Sides that are the same length.
- 2. A closed figure with five sides.
- 3. – points that lie on the same plane.
- 5. Surface planes of three-dimensional shapes.
- 8. is the part of a line that contains an endpoint and all points extending in the other direction.
- 9. a segment – line, ray segment, or plane that divides a segment into two congruent segments.
- 11. A three-dimensional figure on which the faces are triangular and converge to a single point at the top. Pyramids are named after the shape of their base (triangular pyramid, square pyramid, rectangular pyramid).
- 12. A closed figure with six sides.
- 14. A closed figure with seven sides.
- 17. A three-dimensional figure with identical equilateral squares as faces (a cube is also a prism, see square prism below).
- 18. segments – segments that have the same length.
- 20. A two-dimensional shape in which all points on the curved line are equidistant from a center point.
- 21. A two-dimensional, closed, four-sided figure with four right angles.
- 22. The meeting of two faces on a three-dimensional shape.
- 24. Two lines in a two-dimensional space that do not meet (for example, the opposite sides of a square). A parallelogram has two sets of parallel lines.
- 29. – angle whose measure is between 0 degrees and 90 degrees.
- 30. A three-dimensional figure with identical ends. Named after the two-dimensional shape at the ends. For instance, a rectangular prism has identical rectangles at each end.
- 33. A closed four-sided figure with parallel opposite sides. A square is a special kind of rhombus. Sometimes called a diamond.
