Hardly anything on these pages really requires an Official Solution. 1.1-4 just beat to death the script to draw a square, always the first exercise in turtle geometry. 1.1.5(e) sneaks in an actual challenge, namely, drawing an equilateral triangle. Probably by the end of the class period, all the students will have taught each other how to do it, but if not, resist the temptation to tell them, because the rest of this lab is about how to figure out turning angles for arbitrary regular polygons. 2.5 has a solution, below.
The TIF solutions are in separate files:
