I am a foster parent to a 16 year old boy who is just learning geometry. Since I did not have geometry in school, I am learning with him. He has to do an 2 art projects -- one based on .2, .3, or .4; the other based on .5 or .6. I know what a point is in geometry but I do not understand what kind of designs he is supposed to make based on these. Please explain. Thanks.
