I don't know how you prepared it, Jeff, but it is not accurate. Check sides
3,4,5 which should give a 90 dead on. However, since it is for your own
reference, what the hey.
You could do as much and more in a simple spreadsheet application, I think.
How would you use it in grade 7? What are they trying to study? Since you say
they are drawing the triangles, it isn't likely the simplest application,
similarity, so is it trigonometric solution of triangles?
David.
