Diagrams that draw themselves
continues from lesson 5 — values defined earlier in the course stay live here
A geometry cell renders a labelled figure from your numbers — right(a, b) for a right triangle, triangle(a, b, c) for any triangle. The drawing is driven by the variables, so it redraws to scale the instant you change them.
right(leg_a, leg_b)
the same 3-4-5 triangle, drawn to scale
These figures share the document's variables — change leg_a above and the triangle re-proportions here.
