Perhaps I will want to add a "fuzz factor" with deltas for determining whether I have an isosceles or equilateral triangle, respectively.

也许我会加入“误差因素”，和 delta 一起来确定是等腰三角形还是等边三角形。

An equilateral triangle has all sides equal and all angles equal. A right triangle has one Angle equal to 90 degrees.

等边三角形三边相等三内角相等。直角三角形有一个角等于90度。

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。
