  1. 1. Escola la Maquinista SHAPE AND SPACE 3D SHAPES  Three-dimensional shapes, because there are 3 dimensions HEIGHT, WIDTH and DEPTH
  2. 2. Escola la Maquinista SHAPE AND SPACE HEIGHT, WIDTH AND DEPTH
  3. 3. Escola la Maquinista SHAPE AND SPACE BASIC PROPERTIES FACES, VERTICES and EDGES 3D shapes can be described in 3 ways: Faces – the sides of the shape Vertices – the corners Edges – where the faces meet FACES VERTICES EDGES
  4. 4. Escola la Maquinista SHAPE AND SPACE SOME FAMOUS SHAPES CONE Faces – 2 Edges – 1 Vertices - 1
  5. 5. Escola la Maquinista SHAPE AND SPACE CYLINDER Faces – 3 Edges – 2 Vertices - 0
  6. 6. Escola la Maquinista SHAPE AND SPACE SOME FAMOUS SHAPES SPHERE Faces – 1 Edges – 1 Vertices - 0
  7. 7. Escola la Maquinista SHAPE AND SPACE SOME FAMOUS SHAPES SQUARE BASED PYRAMID Faces – 5 Edges – 8 Vertices - 5
  8. 8. Escola la Maquinista SHAPE AND SPACE SOME FAMOUS SHAPES CUBE Faces – 6 Edges – 12 Vertices - 8 SOME FAMOUS SHAPES
  9. 9. Escola la Maquinista SHAPE AND SPACE TRIANGULAR PRISM Faces – 5 Edges – 9 Vertices - 6
  10. 10. Escola la Maquinista SHAPE AND SPACE TRIANGULAR BASED PYRAMID (Tetrahedron) Faces – 4 Edges – 6 Vertices - 4
  11. 11. Escola la Maquinista SHAPE AND SPACE CUBOID (square prism) Faces – 6 Edges – 12 Vertices - 8
  12. 12. Escola la Maquinista SHAPE AND SPACE 3D SHAPES  can be divided in POLYHEDRA and NON POLYHEDRA
  13. 13. Escola la Maquinista SHAPE AND SPACE POLYHEDRA also polyhedrons A polyhedron is a 3d shape with FLAT FACES (from Greek poly- meaning "many" and -edron meaning "face").
  14. 14. Escola la Maquinista SHAPE AND SPACE We name polyhedra according to the NUMBER OF FACES
  15. 15. Escola la Maquinista SHAPE AND SPACE 4 faces TETRAHEDRON 5 faces PENTAHEDRON 6 faces HEXAHEDRON 7 faces HEPTAHEDRON … 20 ICOSAHEDRON
  16. 16. Escola la Maquinista SHAPE AND SPACE Can you name these shapes?
  17. 17. Escola la Maquinista SHAPE AND SPACE POLYHEDRA can be … REGULAR and IRREGUALR
  18. 18. Escola la Maquinista SHAPE AND SPACE REGULAR POLYHEDRA All its faces are regular polygons
  19. 19. Escola la Maquinista SHAPE AND SPACE There are only 9 Regular Polyhedra Tetrahedron Cube Octahedron Dodecahedron Icosahedron Small Stellated Great Great Stellated Great Dodecahedron Dodecahedron Dodecahedron Icosahedron
  20. 20. Escola la Maquinista SHAPE AND SPACE IRREGULAR POLYHEDRA NOT all its faces are regular polygons
  21. 21. Escola la Maquinista SHAPE AND SPACE NON POLYHEDRA also non polyhedrons A polyhedron is a 3d shape with any CURVED FACES
  22. 22. Escola la Maquinista SHAPE AND SPACE The most famous are cone cylinder sphere torus
  23. 23. Escola la Maquinista SHAPE AND SPACE POLYHEDRA NON POLYHYEDRA3D SHAPES (height, width, depth) REGULAR IRREGULAR
  24. 24. Escola la Maquinista SHAPE AND SPACE POLYHEDRONS IN NATURE LIMPET WASP NEST POMEGRANATE PIPE
