Apex (geometry)

square pyramid

In geometry, an apex (Latin for 'summit, peak, tip, top, extreme end;'[1]) is the vertex which is in some sense the highest of the figure to which it belongs.

  • In an isosceles triangle, the apex is the vertex where the two sides of equal length meet, opposite the unequal third side.
  • In a pyramid or cone, the apex is the vertex opposite the base.
