这两个三角形相重合。
For example, the triangle strip (0, 1, 2, 3) will translate to two triangles (0, 1, 2) and (1, 2, 3).
举例来说，三角形带(0,1,2,3)可转换为两个三角形(0,1,2)及(1,2,3)。
A first example is the default picture where it might seem that there are two triangles but in fact only one triangle was drawn.
第一个例子是默认图片里似乎有两个三角形，但实际上只画了一个三角形。
Angle-angle-side congruence. when two triangles have corresponding angles and sides that are congruent as shown below the triangles are congruent .
译：当两个三角形象下面所示有两个角和一个边同时相等时，这两个三角形全等。
Two triangles are congruent if they have two angles and the included side equal.
两个三角形如果有两个角及其夹边对应相等则它们全等。
Two triangles are congruent if they have two angles and the included side equal.
两个三角形如果有两个角及其夹边对应相等则它们全等。
