(7) Division using similar shapes
(i) Non-concrete shapes Although it is easy to create similar shapes in an open space, it is not easy to divide a space with a limited form using similar shapes. However, when we pay attention to the so called geometric
progression, the planing for the divisions will be easier with its advantage
on the diagram processing. Then, we can use a geometric progression that
when the side of the shape is half, the area will be half. The procedure
is simple since we just need to repeat to make the length half of the sides.
