我们学习了对称知识之后,就要利用对称知识解决相关问题.现把轴对称变换典型题的解法归纳如下.一、画轴对称图形例1图1是由半圆和三角形组成的图形,请以AB为对称轴,作出图形的另一半(用尺规作图,只保留作图痕迹,不写作法和证明).
After we study the symmetry knowledge, we must use symmetric knowledge to solve the related problems. We now summarize the solution to the typical problem of axisymmetric transformation as follows. First, the symmetry of the drawing axis. Example 1 Figure 1 is a graphic composed of semicircles and triangles. Please use AB as Axis of symmetry, making the other half of the graph (map with rulers, keeping only traces of drawings, not writing and proof).
