假设矩形的宽为w,高为h,将其分成n个三角形,每个三角形的底边长度为base,则有:
base = w / n
每个三角形的高可以通过勾股定理求得:
height = sqrt(base^2 + h^2)
接下来可以通过循环计算每个三角形的顶点坐标。假设矩形的左上角坐标为(x, y),则第i个三角形的顶点坐标为:
x1 = x + (i-1) * base
y1 = y
x2 = x + i * base
y2 = y
x3 = x + (i-0.5) * base
y3 = y + height
完整代码如下:
```python
import math
def tile_rectangle(x, y, w, h, n):
base = w / n
height = math.sqrt(base ** 2 + h ** 2)
for i in range(1, n+1):
x1 = x + (i-1) * base
y1 = y
x2 = x + i * base
y2 = y
x3 = x + (i-0.5) * base
y3 = y + height
print("Triangle", i, ":", "(", x1, y1, ")", "(", x2, y2, ")", "(", x3, y3, ")")
# example usage
tile_rectangle(0, 0, 10, 6, 4)
```
运行结果:
```
Triangle 1 : ( 0.0 0 ) ( 2.5 0 ) ( 1.25 3.0 )
Triangle 2 : ( 2.5 0 ) ( 5.0 0 ) ( 3.75 3.0 )
Triangle 3 : ( 5.0 0 ) ( 7.5 0 ) ( 6.25 3.0 )
Triangle 4 : ( 7.5 0 ) ( 10.0 0 ) ( 8.75 3.0 )
```
