This is one of 12 video lectures in a course called “The Platonic Solids (using a model)”. All these videos are on a Youtube playlist of that name.
This is number 10 called “Duality", which explains what is meant by a dual pair of Platonic Solids
The model can be made by downloading the worksheets from my website www.mathswithgeoboards.com , cutting out the shapes and simply putting them together with sticky tape.
The accompanying worksheet can also be downloaded from www.mathswithgeoboards.com
This course is one in a series of “Hands-on Maths” courses. These can be accessed from my website , or on Youtube here. They are also on www.udemy.com All courses are free.
