I was thinking of getting Key to Geometry and seeing which level to start with. So I view the sample page for level 1 and I am a little puzzled by this question.
Please tell me if you can understand question 1 on page 37:
When they say "the ray through each segment" do they mean the ray that would be there if in place of each segment we drew a ray?
That ist he closet interpretation I can make that would make sense. But then why do they say "draw a small arc" - do they mean that you should draw 7 small arcs, one through each segment (I mean through each invisible ray that would have extended from the segment, had the segment been a ray)?
This is the kind of stuff that I have to make sure is very clear before handing over to dd.
