The birth of a True Equilateral Triangle from Isosceles parents is the subject of rejoicing in our country for many furlongs around.

一对等腰三角形父母如果生出真正的等边三角形，这在方圆百里都是件大喜事。

In addition to creating zone of stability in the Moon's orbit in which to build permanent space habitats, the Lagrange librations points have a unique geometry, such that three of the points form an equilateral triangle and two of those three points form congruent equilateral triangles with the Earth and Moon.

除了在月球轨道上建立稳定区域以便建造永久的太空生活地外，拉格朗日平衡点也具备了独特的几何，像是三点形成等边三角形，或者是有两点能跟地球与月球形成全等的等边三角形。

此外，可以在月球的轨道创造稳定区域，来建立永久性的太空栖息地。拉格朗日点有一个独特的几何形状，例如有三个点（L3、L4、L5），形成等变三角形。而这三个点中又有两个（L4、L5），和地球月亮构成两个等边三角形。

In this paper,the important method of R-r-s is used to establish two inequalities for the medians and angle-bisector s of acute triangles,and two inequalities conjectured are proposed and verified with the computer.

应用三角形不等式中重要的R-r-s方法，证明了锐角三角形的中线与内角平分线的两个不等式，提出了两个未解决的猜想不等式。

Because be in put to good use this movement when, oneself formed a triangle between double leg, and we know, the triangle is the stablest structure, name " triangle lock " so.

由于在施展这个动作的时候，自己双腿之间形成了一个三角形，而我们都知道，三角形是最稳定的结构，故而取名&三角锁&。
