全等三角形是中考重要考点之一,是后面学习四边形、相似形等相关内容的基础.利用全等三角形的对应边相等、对应角相等的性质,可以得出相等的线段和相等的角.下面列举的是近两年的部分中考题,让我们一起来感受全等三角形的知识在中考中的应用.例1已知:如图1,AB=AD,AC=AE,∠BAD=∠CAE.求证:BC=DE.(常州市2008)证明∴∠BAD=∠CAE, The congruent triangles are one of the most important test centers in the senior high school entrance examinations and the basis for learning about the related quadrilaterals, similar shapes, etc. Equivalent line segments and equal angles can be obtained by using the equal sides of the congruent triangles and the corresponding angles. As shown in Figure 1, AB = AD, AC = AE, ∠ BAD = ∠ CAE. As shown in Figure 1, AB = AD, AC = AE, ∠ BAD = ∠ CAE. Proof: BC = DE. (Changzhou 2008) Prove ∴∠ BAD = ∠ CAE,
