代码如下: func GetTriangleAreaByVector(x vector.Vector3,y vector.Vector3,z vector.Vector3) float64 { //根据三角形三个点坐标求面积 //先算三角形三个边的长度 a := vector.GetDistance(x,y) b := vector.GetDistance(x,z) c := vector.GetDistance(y,z) s := (a + b + c) / 2 area := math.Sq
编写一个控制台应用程序,输入三角形或者长方形边长,计算其周长和面积并输出. 代码如下: using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; namespace Testing1_1 { class Program { static void Main(string[] args) { //三角形 长方形的变量 int
