While it may be relatively easy to split a square or rectangle into two halves that are roughly the same size, have you ever actually tested your brain in its ability to do so?
However, there are three distinct ways of partitioning a square into three similar rectangles: [1] [2] The trivial solution given by three congruent rectangles with aspect ratio 3:1. The solution in which two of the three rectangles are congruent and the third one has twice the side length of the other two, where the rectangles have aspect ...
Splitting the thin parallelogram area (yellow) into little parts, and building a single unit square with them The key to the puzzle is the fact that neither of the 13×5 "triangles" is truly a triangle, nor would either truly be 13x5 if it were, because what appears to be the hypotenuse is bent.
This rectangle can then be partitioned into a square and a similar rectangle and this rectangle can then be split in the same way. After continuing this process for an arbitrary number of steps, the result will be an almost complete partitioning of the rectangle into squares. The corners of these squares can be connected by quarter-circles.
By the Wallace–Bolyai–Gerwien theorem, a square can be cut into parts and rearranged into a triangle of equal area.. In geometry, the Wallace–Bolyai–Gerwien theorem, [1] named after William Wallace, Farkas Bolyai and P. Gerwien, is a theorem related to dissections of polygons.

Men's college basketball plays two 20 minute halves. Women's play four 10-minute quarters. Explaining the difference:
One of the reasons for creating sections of 640 acres (260 ha) was the ease of dividing into halves and quarters while still maintaining a whole number of acres. A section can be halved seven times in this way, down to a 5-acre (2 ha) parcel, or half of a quarter-quarter-quarter section—an easily surveyed 50-square-chain (2 ha) area. This ...
