Perhaps I will want to add a "fuzz factor" with deltas for determining whether I have an isosceles or equilateral triangle, respectively.(也許我會加入“誤差因素”，和delta一起來確定是等腰三角形還是等邊三角形。)

Using the method of simulated shell, non-linear dynamic differential equation of three-dimensional single-layer shallow lattice shell with equilateral triangle mesh is established.(用擬殼法建立了正三角形網格的三向扁錐面單層網殼的非線性動力學微分方程。)

An equilateral triangle has all sides equal and all angles equal. A right triangle has one Angle equal to 90 degrees.(等邊三角形三邊相等三內角相等。直角三角形有一個角等于90度。)

The program then states whether the triangle is scalene, equilateral, or isosceles."(然后程序會判斷三角形是否為不等邊三角形，等邊三角形或者等腰三角形。)

For example, the triangle values 2, 2, 2 and 3, 3, 3 are both equilateral.(例如，三角形的三條邊分別是2,2,2和3,3,3，它們都是等邊三角形。)

Each face is an equilateral triangle and three faces meet at each vertex.(每一個面是正三角形并且于每一個頂點處有三個面相交。)

The three guide rods are set parallel mutually between the top cross beam and the lower piston and distributed in an equilateral triangle.(在該三根導桿的上端固定連接有所述頂橫梁；在該三根導桿的下端則固定連接有所述活塞；)

It is called Equilateral triangle that a triangle has equal legs.(三條邊都相等的三角形叫做等邊三角形。)

Nine PZT actuators are distributed among four platforms, and in each layer there are three PZT actuators placed on the vertexes of an equilateral triangle.(在四層平行平板間并列分布九個PZT微驅動器，每層的三個驅動器擺放在一個正三角形的三個頂點上。)

Conclusions in general endometrial cavity is mostly isosceles triangle or equilateral triangle.(結論普通人群宮腔形態以形態規則的等腰三角宮腔和等邊三角宮腔為主。)
