Are all the squares rhombuses

short answers for big questions

Short answer: yes, they are. Long answer: the definition of a rhombus tells us that it is a quadrilateral (a polygon containing 4 sides) and so it has the following features:

  • Its internal diagonals are perpendicular among themselves;
  • rhombuses
  • All its sides are congruent among themselves (they have the same length);
  • The opposite internal angles are congruent (they have equal measures);
  • rhombuses
  • The adjacent internal angles are supplementary (their sum is 180º).
  • rhombuses
As a matter of fact, the square also fulfils all these requirements. Therefore, it is also considered to be a rhombus.

And, are all the rhombuses squares?

The contrary is not true. For a polygon to be considered a square, besides all the requirements announced before, it is also required to possess the following feature:

  • The internal angles must be right angles (90ºdegrees).
In conclusion, it cannot be said that all the rhombuses are squares, since not all the rhombuses possess this specific feature.
