Not drawn accurately
A warning that the diagram is approximate. Do NOT measure with a ruler — use the given values only.
Definition
When a diagram is labelled "not drawn accurately", you must rely entirely on the values printed on the diagram. Measuring an angle or length from the diagram is forbidden — the diagram is deliberately misleading.
Common confusion
Students measure with a ruler or protractor and use the measurement in their working. This loses every mark on the question.
