Lego Triangles? 

The Problem:

 You need to make two triangles out of Lego (or Meccano etc).

They must be mathematically similar.

 A         You have five pieces � of length 2,4,5,6 and 12cm. 

What must be the length of the sixth piece, for you to be able to make your two triangles?

            Do you have any choice?

 

B         Does it make any difference to your task if the five lengths are 2,3,4,41 and 6cm?

            Are there any choices this time?!

 

C         What difference does it make to your task if the five lengths are 1,2,3,6 and 9cm?
