'LOGO Challenge - Triangles' printed from http://nrich.maths.org/

Show menu


The theme in the rest of the magazine is TRIANGLES. But triangles are available in all sizes and in 'several' varieties.

Similarly this month LOGOland will focus on triangles - equilateral triangles and a tri-radial variant (Fig.2) and triquetral variant (Fig. 3) that can be derived from the equilateral triangle.

Just how many types of triangles can you name/ list?

What follows below is for those who feel comfortable using 'primitives', those who have possibly written procedures and probably produced small programs.

Can you replicate the patterns below and/or create related patterns? But, as before, the challenge will be to produce elegant solutions. -- Elegance here implies simplicity!
