Topics in Recognition of Solids

1

1. Identifying 2D and 3D Figures

  • A straight line has only one dimension: length.
  • A rectangle has two dimensions: length and breadth.
  • All rectilinear figures such as square, parallelogram, and trapezium are two-dimensional figures.
2

2. Cube, Cuboid, Cylinder, and Cone

  • A cube is a symmetrical three-dimensional shape, solid or hollow, contained by six equal squares.
  • A cube is a cuboid with all sides equal, i.e. length = breadth = height.
  • Each face of a cube is a square and all six faces are congruent.
3

3. Faces, Edges, and Vertices

  • A cuboid has six rectangular faces, twelve edges, and eight vertices.
  • A cube has six faces, twelve edges, and eight corners, same as a cuboid.
  • Cube has V=8, E=12, F=6.

4. Euler's Formula

  • Euler's formula is V + F - E = 2 for a polyhedron.
  • V means number of vertices.
  • E means number of edges.
