Line 58: Bisect {{math\|AB}} with line {{math\|OPC}}, {{math\|AC}} becomes one side of [[dodecagon]] (12-gon), let its length be {{math\|m}}. Let the length of {{math\|PC}} be {{math\|j}} and the length of {{math\|OP}} be {{math\|G}}. {{math\|~~AOP~~APO}}, {{math\|APC}} are two right angle triangles. Liu Hui used the [[Pythagorean theorem]] repetitively: : <math>{} G^2 = r^2 - \left(\tfrac{M}{2}\right)^2</math>
