What is in this set

The numbers in this set run from 0 to 0.
Every problem in it will use a shape whose angles are all the same.
A careful solution takes 3 written steps on average.
The mistake this set invites most often, in 73% of the problems: that is one angle of the turn outside the shape; the inside angle is what is left of the straight line.
Answers are a whole number.

Drawing 240 problems from this page produced 4 different ones, 2% — so a sheet of 20 will come back to a problem you have seen — there are only so many sensible ones of this kind.

The same skill, harder or easier

We would put this in front of a grade 8 class. That is our judgement, not a standard, and it is printed here so you can disagree with it. Everything else we put in that year.
