Hello!
I have one question.
I have given 5 coordinates:
0 0
2 0
1 1
1 -1
3 -1
The question is how many right angles can I create with these coordinates?
I know one way out, but it is pretty complicated.
C52=5!/(2!*3!)=5*4*3!/(2!*3!)=10
And try every single combination (finding the sides of the triangles, there are 10 of them). Is there any simpler way?
Thanks in advance.
Regards.
