A rhombus is a special geometrical shape characterised by the fact that its opposite sides are parallel and of equal length, and the opposite angles are equal and the adjacent angles are complementary. Not really exciting. So a square is a special case of the rhombus. In everyday life, it appears in architecture: there are roofs, tiles, etc. that are laid out in the shape of a rhombus, and rhombuses make it possible to cover the entire surface of a floor or roof, for example. It can also be found in the digital environment: as a hashtag on social media. In German language the Word for rhombus is hidden in the German corresonding word "familiar". It makes up half of the letters, or 50%. Without it, some five letters would remain without sense. Useless. What is it about you that gives substance and stability to your feeling of familiarity!?
I wish you an extraordinary day!
