Key Topics to Revise

1

Pyramids - Structure and Properties

  • Base edges: sides of the base polygon; Lateral edges: edges of triangular faces
  • Height: perpendicular distance from apex to base
2

Cones - Circular Base Pyramids

  • A cone is like a pyramid with a circular base
  • Can be formed by rolling a sector of a circle
  • Radius of sector becomes slant height of cone
3

Spheres - Perfect Round Solids

  • All points on sphere surface are equidistant from center
  • No flat surfaces - only curved surface
  • Cannot be unfolded flat like other solids
4

Problem-Solving Strategies and Applications

  • Melting and recasting problems: equate volumes before and after
  • Maximum/minimum problems: use relationships between dimensions
  • Combined solids: break into component parts
