Python 计算三角形面积 三角形是由同一平面内的三条线段首尾顺次相接所组成的封闭图形。可用海伦公式通过三角形三条边计算其面积。
那个类有相关的值,比如name和numberOfSides。那个类也有相关的方法,比如findArea或者findPerimeter。shape类有子类,更具体。正方形是一个shape对象,其值shapeType等于square,numberOfSides等于4。它的findArea方法获取lengthOfSides值并求平方。同时,triangle对象对于name、shapeType、numberOfSides有不同的值,其findArea方...
题目地址:https://leetcode.com/problems/largest-triangle-area/description/ 题目描述 You have a list of points in the plane. Return the area of the largest triangle that can be formed by any 3 of the points. Example: Input: points =[[0,0],[0,1 ...

pip install triangle 这个命令会从Python包索引(PyPI)下载并安装Triangle库及其依赖项。安装完成后,就可以在Python脚本中导入并使用它了。 常用接口的使用方法 Triangle库提供了一系列的函数来处理三角形的计算问题。下面是一些基本的接口使用方法。 计算三角形面积 要计算三角形的面积,可以使用triangle.area函数。这个函...

dst_image = cv2.resize(image, None, fx=0.5, fy=0.5, interpolation=cv2.INTER_AREA) 如果要放大图像,最好的方法是使用cv2.INTER_CUBIC插值方法(一种费时的插值方法)或cv2.INTER_LINEAR。 如果要缩小图像,通常的方法是使用cv2.INTER_LINEAR。 OpenCV 提供的五种插值方法是cv2.INTER_NEAREST(最近邻插值),cv2...
'side2', and 'side3' fields. We also define a function "triangle_area()" that takes a "Triangle" NamedTuple as input and calculates its area using Heron's formula. Next, we create an instance of the "Triangle" NamedTuple and use the "triangle_area()" function to calculate its are...
