Shapes

A correct set of solutions was sent in by Christina (Malborough Primary School, UK), Ceren, Idi, Ece, Eda and Ece O (Private IRMAK Primary & Secondary School, Istanbul, Turkey).

Some managed to find two different ways to halve the orange S shape, and Jason (Priory School) found all four ways.

Evren and Christian (Private IRMAK Primary & Secondary School, Istanbul, Turkey) sent in one that no-one else found:

Shapes

Thomas (Tattingstone School UK) says there are an infinite number of lines that can be drawn like the ones below.

Shapes

What do think? Are there more solutions for this shape?

Why are there so many for this one and not the other shapes?
