Work Step by Step
Based upon the hypothesis of a theorem, drawings of different students do not have to be identical.
As long as the drawings uphold the statement of the hypothesis, different students can produce drawings which differ in insignificant ways. For example, different students can use different labels for vertices, produce diagrams of different sizes, use different colors of ink, use different drawing styles, etc...
As long as the essential information satisfies the hypothesis, then variations in drawings are acceptable.
