三角形的

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。

Diagram 3 shows triangles E, F, G and H drawn on equilateral triangles of same size.

图 3 显示三角形 E，F，G和 H，它们分别是画在同样大小的等边三角形上。

Triangle with two equal sides is called isosceles triangle.

*有两条边相等的三角形叫做等腰三角形。

Isosceles triangle: move the yellow dot on one vertex to modify the triangle type.

等腰三角形：移动顶点上的黄点修改三角形类型。

The program incorrectly classifies this triangle as a scalene triangle instead of classifying it as an isosceles triangle.

程序错误的把这个等腰三角形划分成了不等边三角形。

However, misapplication of area formulas has been a considerable problem.

长方形面积问题较易、三角形面积问题较难，尤其对於三角形，边与高的概念容易混淆。

Point data is reorganized by generating index list respectively for geometric coordinates, texture coordinates and normal vectors. Triangular facet data is reorganized by collecting the faces with the same material attribute and generating triangle strip. Texture image data is reorganized in the format of DDS.

采用对几何坐标数据、纹理坐标数据和法线向量数据分别建立索引列表的方式重组点数据，通过集中存储相同材质面片和生成三角形条带来重组三角形面片数据，采用DDS图像压缩格式重组纹理数据。

Triangle with one obtuse angle is called obtuse angle triangle.

*有一个角是钝角的三角形叫做钝角三角形。

Sepals triangular to ovate-triangular; leaf blades abaxially densely white tomentose, shallowly obtusely serrate.

萼片三角形到卵形三角形；浓密白色被绒毛的叶片背面，浅钝锯齿。
