  • Welcome to [math.se] SE. Take a [tour]. You'll find that simple "Here's the statement of my question, solve it for me" posts will be poorly received. What is better is for you to add context (with an [edit]): What you understand about the problem, what you've tried so far, etc.; something both to show you are part of the learning experience and to help us guide you to the appropriate help. You can consult this link for further guidance. – Shaun Mar 07 '22 at 17:36

    Could you say which book it is and its date of edition ? – Jean Marie Mar 07 '22 at 21:41

It is not sure at all it is a computerized drawing!

Some 60 and even 50 years ago, there were graphic designers able to use in a baffling way decals/transfers representing graphic items such as geometrical shapes, arrows etc. + of course scissors and glue to give a first figure.

Then this figure was photographed, and it is (a generally resized version of) this photography that was inserted into the text.

See here or there for example.
