问题与情境前面我们通过探究得知:三边对应相等的两个三角形全等;两角及其夹边或两角及一角的对边对应相等的两个三角形全等;三个角对应相等的两个三角形不全等．那么给定角形的两边及一角时,所得到的三角形都全等吗? Problems and Situations In front of us, we learned that: three sides are equal to two equal triangles congruent; two corners and their clipping edges or two corners and one corner’s opposite edges are equal to two equal triangles; the three angles are equal to each other Two triangles are not equal. Then, when the sides and the corners of a given corner are given, are all the triangles obtained equal?
