  2. In problem type three the common regular shapes used are squares, rhombi and regular pentagons.

Real-life Applications

  1. The ancient Egyptians from over 4000 years ago were very good at shapes and geometry. Every time the Nile burst its banks and flooded the planes, they had to use geometry to measure their gardens and fields all over again.
  2. Architects use shapes to construct houses and skyscrapers.
