20170807 23:10:42 +0100  asked a question  How to generate graphs random geometric shapes? I would like to create practice problems, rather than reusing old exam questions, to help my students practice solving geometric problems. I would like to use sagetex to produce random variations similar the questions I have listed below. I would supply examples of the pictures, but I do not have enough points to post pictures. I am wish to be able to make one worksheet where each time it is printed, the values would be randomly assigned and graph would be produced. I know how to assign a random integer value to a variable; however, how to produce the graphs I have no understanding of how to achieve that. Thus for each of the example problems how to make the graph and how to assign the random variability to that graph. Example questions The diagram below shows a childâ€™s toy which is made up of a circular hoop, centre O, radius 7 cm. The hoop is suspended in a horizontal plane by three equal strings XA, XB, and XC. Each string is of length 25 cm. The points A, B and C are equally spaced round the circumference of the hoop and X is vertically above the point O.
ABCDV is a solid glass pyramid. The base of the pyramid is a square of side 3.2 cm. The vertical height is 2.8 cm. The vertex V is directly above the centre O of the base.
