等边三角形

It is called Equilateral Triangle that a triangle has equal legs.

三条边都相等的三角形叫做等边三角形。

Take for example an equilateral Triangle -- who represents with us a Tradesman of the respectable class.

现在，拿一个等边三角形做实验--呈现在我们眼前的等边三角形，他来自受人尊敬的阶层，是一位零售商。

Like Picture 2, a triangle with three same sides is called an equilateral triangle.

象（2）一样，有三条边相等的三角形叫做等边三角形。又叫正三角形。

Triangle with three equal sides is called equilateral triangle.

*三条边都相等的三角形叫做等边三角形。

However, one who demonstrates this for scalene or equilateral triangles does so from principles that are necessarily not first principles.

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。

If appear special triangle, wait like isosceles right-angled triangle or equilateral triangle, so the problem can apply special methodological processing.

假如出现非凡三角形，如等腰直角三角形或等边三角形等，那么新问题就能运用非凡的方法处理。
