Cutting Candles
Peer reviewed Peer reviewed
Ranucci, Ernest R. – Mathematics in School, 1973
Different regular-polygon-shaped candles wound with a sheet of paper are cut through obliquely. When the papers are unwound, unique patterns are revealed. Investigation of these patterns leads to the discovery of geometric concepts. (JP)
