DaveC426913 replied to the thread Geometric Game: Fun With Matches (Safe!).I have demonstrated that it is. What is "exactly three equilateral triangles"? Even that requires lot of assumptions. You made them... -

DaveC426913 replied to the thread Geometric Game: Fun With Matches (Safe!).That's my point. Ambiguity leads to subjective intepretation. Yup. That's an interpretation. Yup. So is that. Yes. Which would still... -
