然后程序会判断三角形是否为不等边三角形，等边三角形或者等腰三角形。
The program then states whether the triangle is scalene, equilateral, or isosceles."
不过，一个人特别论证不等边三角形或等边三角形，是从必然非第一原理论证。
However, one who demonstrates this for scalene or equilateral triangles does so from principles that are necessarily not first principles.
当设计这个测试时，您会瞬间看到三类输入输出数据：不等边三角形，等边三角形或者等腰三角形。
When designing tests for this, you immediately see three classes of input and output values: scalene, equilateral, and isosceles.
给儿童介绍不同种类的三角形，如等边三角形、等腰三角形、不等边三角形和直角三角形。
Introduce children to different kinds of triangles, such as equilateral, isosceles, scalene, and right.
在教室和户外发现这些图形之后，儿童可以用彩色胶带勾勒出这些三角形，例如，他们可以用红色胶带做直角三角形，用蓝色胶带做不等边三角形。
After finding them in the classroom or outdoors, children can outline the triangles with colored tape. For example, they might make right triangles red and scalene triangles blue.
