How this data is usedHelp
A triangle needs three fully drawn straight sides. A rectangle needs four fully drawn sides and four right angles; squares count as rectangles. A side may continue through an intersection, but it cannot bridge a gap. Count each outline once. Higher levels add multiple bases, crossed diagonals and staggered partial partitions. These original puzzles are not a standardized assessment.
Each round has six questions and no time limit. Choosing an answer locks it. Review the steps, then move to the next question. Finish all six to save the round. Active time includes reviewing the steps, but does not count time when this page is hidden. Speed does not affect your score.
Use Tab and Enter or Space to choose an answer. The number keys also select answers, except when another control is focused. After an answer, Enter goes to the next question.
