圆规画圆信手拈来,水到渠成；“用圆规画蛋”或“近似画圆”怎么样呢?尺规画蛋作法(如图1)①作两个半径相等的圆⊙A、⊙B,使圆心B在⊙A上；②以AB为直径作⊙O交公共弦CD于E；③连结AE并延长交⊙A于点F,连结 The compass will be well-rounded, and the water will follow; “How to draw an egg with a compass” or “approximate drawing circle”? How does the ruler paint the egg? (Figure 1) 1 Make two circles of equal radius A and B so that the center of the circle B On ⊙A; 2 for AB diameter for ⊙O to turn the common chord CD on E; 3 for AE and extend for ⊙ A at point F, link
