vector triangle

This paper explores into the distance formula between median point, orthocenter, circumcenter and inner point of triangle by means of two related formulas of vector methods.

应用两个向量法相关公式探讨了三角形重心、垂心、外心以及内心之间的距离公式。

The two-dimension polyline set, triangle mesh and point sampled model are primary methods of geometric model representation and are widely employed to represent the vector map and three-dimension geometric model corresponsively.

二维折线集、三角网格和点是几何模型表示中的基本元素，分别被广泛用于二维矢量地图和三维物体模型的表示。

The profit signal and noise vectors are orthogonal to each other, so the variation vector is the hypotenuse in a right triangle.

有效信号适量和噪声信号适量相互正交，所以变量矢量是直角三角形的斜边。

For instance, it's also the square of the Euclidean norm on R2, the length of a two-dimensional vector, a part of the triangle inequality, and quite a bit more.

例如，R2的平方、二维向量的长度、三角不等式等都存在勾股定理。
