  1. 2. 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. A hexagonal prism has identical hexagons at each end: triangular prism square prism (also called a cube) rectangular prism pentagonal prism hexagonal prism heptagonal prism octagonal prism.
  2. 9. called a diamond.
  3. 12. 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.
  4. 14. A three-dimensional figure with identical equilateral squares as faces (a cube is also a prism see square prism below).
  5. 16. Surface planes of three-dimensional shapes.
  6. 17. A two-dimensional closed four-sided figure with four right angles.
  7. 19. Two lines that meet to make a corner.
  8. 20. 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).
  9. 22. A specific position on a line plane or in space.
  10. 24. terms, Words and phrases that describe the location of an object in relation to other objects, including words like on under on top of next to in front of behind beneath underneath inside outside at/on the bottom/top between and adjacent to (this is just a sample there are many more).
  11. 25. A closed figure with six sides.
  12. 26. A closed four-sided figure with parallel opposite sides. A square is a special kind of rhombus.
  13. 28. Without a curve.
  14. 29. 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.
  15. 30. 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.

  1. 1. A round body whose surface is at all points equidistant from the center.
  2. 3. A special type of rectangle that has equilateral (same length) sides and parallel opposite sides.
  3. 4. A solid or hollow object that tapers from a circular or roughly circular base to a point.
  4. 5. Line segments in geometric figures that compose the exterior of the object.
  5. 6. A closed figure with seven sides.
  6. 7. The meeting of two faces on a three-dimensional shape.
  7. 8. A two-dimensional shape in which all points on the curved line are equidistant from a center point.
  8. 10. A closed figure with eight sides.
  9. 11. A closed figure with three sides.
  10. 13. Sides that are the same length.
  11. 15. Identical in size and shape.
  12. 18. Having curvy or undulating attributes (e.g. ocean octopus tentacles).
  13. 21. 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.
  14. 22. An informal word to describe angles of objects.
  15. 23. Having a plane-like quality.
  16. 27. A closed figure with five sides.
