在这里我们将对两例常见轴对称作图的问题进行深入的探究,主要关注其“退化”的情况.问题1已知锐角∠EOF及角内一点A,在角的两边上分别求作点B、C使得AB+BC+AC最小.图1作法如图1,作点A关于OE的对称点M,作点A关于OF的对称点N Here we will explore the two cases of common axisymmetric mapping in-depth study, the main concern of its “Degradation ” problem 1 known acute angle ∠ EOF and angle within a point A, respectively, on both sides of the corner Determine point B, C such that AB + BC + AC minimum Figure 1 practices as shown in Figure 1, for point A on the OE symmetry point M, for point A on the OF symmetry point N
