几何知识是初中数学的一个重要部分.其中,几何作图是几何知识的一个重要内容,它是学好几何的必备技能.几何作图不仅可以帮助学生提高识图能力,还可以帮助学生提高分析问题和解决问题的能力,在几何作图的过程中,可以让学生加深对题目的理解.复杂的几何作图,都是由一些基本作图组成的.常见的基本作图有根据条件作三角形;作角平分线;作线段垂直平分线;作轴对称图形;作旋转图形等等.在复杂几何问题 Geometric knowledge is an important part of junior high school mathematics, in which geometry drawing is an important part of geometric knowledge and is an essential skill for learning geometry.Geometry drawing not only helps students to improve their cognitive ability, but also helps students to improve their analysis Problems and problem-solving skills, in the process of geometry drawing, allowing students to deepen the understanding of the subject.Complex geometric drawing, are composed of some basic drawings.Common basic drawing according to the conditions for the triangle ; Angle bisector; Vertical bisector for line segments; Axisymmetric graphics; Rotation graphics, etc. In complex geometry problems
