用于计算三个点之间的角度的Python代码(后面的长坐标)

import math

def calculate_angle(point1, point2, point3):
    # 计算向量
    vector1 = [point1[0] - point2[0], point1[1] - point2[1]]
    vector2 = [point3[0] - point2[0], point3[1] - point2[1]]

    # 计算向量的长度
    length1 = math.sqrt(vector1[0] ** 2 + vector1[1] ** 2)
    length2 = math.sqrt(vector2[0] ** 2 + vector2[1] ** 2)

    # 计算向量的点积
    dot_product = vector1[0] * vector2[0] + vector1[1] * vector2[1]

    # 计算角度（弧度）
    angle_rad = math.acos(dot_product / (length1 * length2))

    # 转换为角度（度）
    angle_deg = math.degrees(angle_rad)

    return angle_deg

# 示例数据
point1 = [0, 0]
point2 = [1, 0]
point3 = [1, 1]

# 计算角度
angle = calculate_angle(point1, point2, point3)
print("角度为:", angle)
