证明两条线段相等是平面几何证明题中很重要的一类题型，也是几何证题的基础．在《三角形》这一章中，我们学习了几种证明两条线段相等的方法，本文对此进行归纳总结，供同学们参考．1．通过证明三角形全等来证明两条线直相等是《基本的方法．可证两米线段是全等三角形的对应边 It is proved that the equality of two line segments is an important type of problem in the plane geometrical proof, and it is also the basis of the geometrical proof. In the “Triangle” chapter, we learned several ways to prove that two lines are equal. This article summarizes this for students’ reference. 1. By proving that the triangle is congruent it is proved that the two lines are equal to each other "basic method. Can prove that the two-meter segment is the corresponding edge of the equal triangle
